Switch with if else if else and loops inside case

Question

For the purpose of my question I ve only included case 1  but the other cases are the same  Let s say value is currently 1  we go to case 1 and our for loop goes through the array to see if each element matches with the whatever value variable  In this case if it does  we declare the value variable to be equal to 2  and we break out of the loop  The problem is that when i highlight the other break in eclipse   it says that the breaks are attached to the for statement as well  but i only wanted the for statement to be attached to the if statement  not the else if statements as well  I thought because there are no brackets for the for statement that it would only loop for the if statement but eclipse says otherwise else if also loops from 0 to the length of the array       switch  value      case 1       for  int i   0  i  lt  something in the array length  i            if  whatever value     something in the array i                 value   2             break            else if  whatever value    2               value   3             break            else if  whatever value    3               value   4             break                 break    case 2        code continues

Your problem      I think is that your for loop is encompassing all of the if  else if stuff - which acts like one statement  like hoang nguyen pointed out   Change to this  Note the brackets that denote the code block on which the for loop operates and the change of the first else if to if   switch value        case 1          for int i 0  i lt something in the array length i                  if whatever value   something in the array i                      value 2                  break                                    if whatever value  2                value 3              break                    else if whatever value  3                value 4              break                    break        case 2   code continues

Seems like kind of a homely way of doing things  but if you must    you could restructure it as such to fit your needs   boolean found   false   case 1   for  Element arrayItem   array        if  arrayItem    whateverValue            found   true               else if       if  found        break    case 2

If you need the for statement to contain only the if  you need to remove its else  like this   for int i 0  i lt something in the array length i        if whatever value   something in the array i                  value 2          break               this  else  must go       if whatever value  2                value 3          break             else if whatever value  3                value 4          break

but i only wanted the for statement to be attached to the if statement  not the else if statements as well    Well get rid of the else then   If the else if is not supposed to be part of the for then write it as              for int i 0  i lt something in the array length i                    if whatever value   something in the array i                                          value 2                      break                                if whatever value  2                               value 3                  break      redundant now                          else if whatever value  3                               value 4                  break      redundant now                Having said that    it is not at all clear what you are really trying to do here   not having the else part in the loop doesn t seem to make a lot of sense here  a lot of people  myself included  think it is to always use braces     so that people don t get tripped up by incorrect indentation when reading your code    And in this case  it might help us figure out what you are really trying to do here        Finally  braces are less obtrusive if you put the opening brace on the end of the previous line  e g     if  something         doSomething          rather than     if  something            doSomething

In this case  I d recommend using break labels   http   www java-examples com break-statement  This way you can specifically call it outside of the for loop
