Control Constructs

• Java supports a complete set of control constructs:
  • if-then-else
  • switch
  • while loops (both top test and bottom test)
  • for-loops
  • try-catch blocks (for exception handling)
• break used to exit from a switch or loop statement
• continue used within looping constructs to advance to the next iteration
• Both break and continue may optionally indicate which construct they apply to (useful in nested constructs)
• There is no goto statement in Java
• The return statement is used to exit a method
  • No return value is specified for void methods
  • Otherwise, expression must be of same type as method return type
