The  break  command does not work within an  if  statement   If you remove the  break  command from your code and then test the code  you should find that the code works exactly the same without a  break  command as with one    Break  is designed for use inside loops  for  while  do-while  enhanced for and switch

Because your else isn t attached to anything  The if without braces only encompasses the single statement that immediately follows it    if  choice  5        System out println  End of Game n Thank you for playing with us         break    else      System out println  Not a valid choice  n Please try again    n        Not using braces is generally viewed as a bad practice because it can lead to the exact problems you encountered   In addition  using a switch here would make more sense   int choice  boolean keepGoing   true  while keepGoing        System out println  --- gt  Your choice          choice   input nextInt        switch choice                case 1               playGame                break          case 2               loadGame                break             your other cases                        case 5               System out println  End of Game n Thank you for playing with us                 keepGoing   false              break          default              System out println  Not a valid choice  n Please try again    n                         Note that instead of an infinite for loop I used a while boolean   making it easy to exit the loop  Another approach would be using break with labels

The issue is that you are trying to have multiple statements in an if without using     What you currently have is interpreted like   if  choice  5         System out println           break  else                 You really want   if  choice  5         System out println             break    else                 Also  as Farce has stated  it would be better to use else if for all the conditions instead of if because if choice  1  it will still go through and check if choice  5  which would fail  and it will still go into your else block   if  choice  1             else if  choice  2             else if  choice  3             else if  choice  4             else if  choice  5                 else               A more elegant solution would be using a switch statement  However  break only breaks from the most inner  block  unless you use labels  So you want to label your loop and break from that if the case is 5   LOOP  for           System out println  --- gt  Your choice          choice   input nextInt        switch  choice                 case 1              playGame                break          case 2              loadGame                break          case 2              options                break          case 4              credits                break          case 5              System out println  End of Game n Thank you for playing with us                 break LOOP          default              System out println                   Instead of labeling the loop  you could also use a flag to tell the loop to stop   bool finished   false  while   finished         switch  choice                                case 5              System out println                    finished   true              break
