The break statement exists the current looping control structure and jumps behind it while the continue exits too but jumping back to the looping condition

Break Statement  Sometimes it   s necessary to exit a loop before the loop has finished fully iterating over all the step values  For example  looping over a list of numbers until you find a number that satisfies a certain condition  Or looping over a stream of characters from a file until a certain character is read   In the following example  we   re using a simple for loop to print out values from 0 to 9   for int i 0  i lt 10  i        System out println i       Output   0 1 2 3 4 5 6 7 8 9   Now if we add a break statement when i  4  our code will break out of the loop once i equals 4  You can use the break statement to break out of for loops  while loops and do-while loops  The break statement will only break out of the current loop  In order to break out of an outer loop from a nested inner loop  you would need to use labels with the break statement   for int i 0  i lt 10  i        System out println i     if i  4        break          Output   0 1 2 3 4   Continue Statement  Java   s continue statement skips over the current iteration of a loop and goes directly to the next iteration  After calling the continue statement in a for loop  the loop execution will execute the step value and evaluate the boolean condition before proceeding with the next iteration  In the following example  we   re printing out all values from 0 to 9 in a loop but we skip over printing out 4   for int i 0  i lt 10  i        if i  4        continue        System out println i       Output   0 1 2 3 5  lt ---- SKIPPED OVER 4 and continued with next loop iteration 6 7 8 9   Loop Label - Break Statement You can use labels within nested loops by specifying where you want execution to continue after breaking out of an inner loop  Normally  the break statement will only break out of the innermost loop so when you want to break out of an outer loop  you can use labels to accomplish this  essentially doing something similar to a goto statement   The following example uses 3 loops  all nested within each other  Since there   s no way completely break out of the outer most loop from inside the inner most loop  we can use the label    outer1    to accomplish this and specify the label next to the break statement   outer1  for int i 0  i lt 5  i        for int j 0  j lt 4  j          for int k 0  k lt 2  k            System out println       i          j          k               if j    3            break outer1                        Output    0  0  0   0  0  1   0  1  0   0  1  1   0  2  0   0  2  1   0  3  0    Notice how the last line displayed is    0 0     which is where j    3 and that   s where we called    break outer1     to break out of the outer most loop   Loop Labels - Continue Statement  You can also use labels with the continue keyword to continue looping from a specific point  Taking the previous example and just changing one line to specify continue outer1  instead of break outer1  will cause the loop to continue looping from the outer1 label instead of breaking out of the loop  Note how each time continue outer1  is called  the code continues from the outer loop after incrementing the loop index i by 1   outer1  for int i 0  i lt 5  i        for int j 0  j lt 4  j          for int k 0  k lt 2  k            System out println       i          j          k               if j    3            continue outer1                0  0  0   0  0  1   0  1  0   0  1  1   0  2  0   0  2  1   0  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  1  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  1  0  1   1  1  0   1  1  1   1  2  0   1  2  1   1  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  2  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  2  0  1   2  1  0   2  1  1   2  2  0   2  2  1   2  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  3  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  3  0  1   3  1  0   3  1  1   3  2  0   3  2  1   3  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  4  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  4  0  1   4  1  0   4  1  1   4  2  0   4  2  1   4  3  0    Source  Loops in Java     Ultimate Guide

so you are inside a for or while loop  Using break  will put you outside of the loop  As in  it will end  Continue  will tell it to run the next iteration    No point in using continue in if statement  but break  is useful   In switch   case  always use break  to end a case  so it does not executes another case

The break statement breaks out of the loop  the next statement to be executed is the first one after the closing brace   while continue starts the loop over at the next iteration

User · Answer

See Branching Statements for more details and code samples    break     The break statement has two forms  labeled and unlabeled  You saw the   unlabeled form in the previous discussion of the switch statement  You   can also use an unlabeled break to terminate a for  while  or do-while   loop            An unlabeled break statement terminates the innermost switch  for    while  or do-while statement  but a labeled break terminates an outer   statement    continue     The continue statement skips the current iteration of a for  while     or do-while loop  The unlabeled form skips to the end of the innermost   loop s body and evaluates the boolean expression that controls the   loop             A labeled continue statement skips the current iteration of an outer loop marked with the given label

break leaves a loop  continue jumps to the next iteration

To prevent anything from execution if a condition is met one should use the continue and to get out of the loop if a condition is met one should use the break   For example in the below mentioned code    for int i 0 i lt 5 i              if i  3               continue                    System out println i            The above code will print the result   0 1 2 4  NOw consider this code    for int i 0 i lt 5 i                   if i  3                    break                             System out println i                This code will print 0 1 2  That is the basic difference in the continue and break

Consider the following   int n  for n   0  n  lt  10    n        break    System out println n     break causes the loop to terminate and the value of n is 0   int n  for n   0  n  lt  10    n        continue    System out println n     continue causes the program counter to return to the first line of the loop  the condition is checked and the value of n is increment  and the final value of n is 10   It should also be noted that break only terminates the execution of the loop it is within   int m  for m   0  m  lt  5    m        int n      for n   0  n  lt  5    n            break            System out println n     System out println m     Will output something to the effect of  0 0 0 0 0 5

Break Statement  Sometimes it   s necessary to exit a loop before the loop has finished fully iterating over all the step values  For example  looping over a list of numbers until you find a number that satisfies a certain condition  Or looping over a stream of characters from a file until a certain character is read   In the following example  we   re using a simple for loop to print out values from 0 to 9   for int i 0  i lt 10  i        System out println i       Output   0 1 2 3 4 5 6 7 8 9   Now if we add a break statement when i  4  our code will break out of the loop once i equals 4  You can use the break statement to break out of for loops  while loops and do-while loops  The break statement will only break out of the current loop  In order to break out of an outer loop from a nested inner loop  you would need to use labels with the break statement   for int i 0  i lt 10  i        System out println i     if i  4        break          Output   0 1 2 3 4   Continue Statement  Java   s continue statement skips over the current iteration of a loop and goes directly to the next iteration  After calling the continue statement in a for loop  the loop execution will execute the step value and evaluate the boolean condition before proceeding with the next iteration  In the following example  we   re printing out all values from 0 to 9 in a loop but we skip over printing out 4   for int i 0  i lt 10  i        if i  4        continue        System out println i       Output   0 1 2 3 5  lt ---- SKIPPED OVER 4 and continued with next loop iteration 6 7 8 9   Loop Label - Break Statement You can use labels within nested loops by specifying where you want execution to continue after breaking out of an inner loop  Normally  the break statement will only break out of the innermost loop so when you want to break out of an outer loop  you can use labels to accomplish this  essentially doing something similar to a goto statement   The following example uses 3 loops  all nested within each other  Since there   s no way completely break out of the outer most loop from inside the inner most loop  we can use the label    outer1    to accomplish this and specify the label next to the break statement   outer1  for int i 0  i lt 5  i        for int j 0  j lt 4  j          for int k 0  k lt 2  k            System out println       i          j          k               if j    3            break outer1                        Output    0  0  0   0  0  1   0  1  0   0  1  1   0  2  0   0  2  1   0  3  0    Notice how the last line displayed is    0 0     which is where j    3 and that   s where we called    break outer1     to break out of the outer most loop   Loop Labels - Continue Statement  You can also use labels with the continue keyword to continue looping from a specific point  Taking the previous example and just changing one line to specify continue outer1  instead of break outer1  will cause the loop to continue looping from the outer1 label instead of breaking out of the loop  Note how each time continue outer1  is called  the code continues from the outer loop after incrementing the loop index i by 1   outer1  for int i 0  i lt 5  i        for int j 0  j lt 4  j          for int k 0  k lt 2  k            System out println       i          j          k               if j    3            continue outer1                0  0  0   0  0  1   0  1  0   0  1  1   0  2  0   0  2  1   0  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  1  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  1  0  1   1  1  0   1  1  1   1  2  0   1  2  1   1  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  2  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  2  0  1   2  1  0   2  1  1   2  2  0   2  2  1   2  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  3  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  3  0  1   3  1  0   3  1  1   3  2  0   3  2  1   3  3  0   lt ---- CONTINUE WITH LABEL CALLED HERE  4  0  0   lt ---- CONTINUES FROM NEXT ITERATION OF OUTER LOOP  4  0  1   4  1  0   4  1  1   4  2  0   4  2  1   4  3  0    Source  Loops in Java     Ultimate Guide
