  1. Jump Statement • Three jump statements • Break, continue and return

  2. Break and Continue with the nested loop result: j 1 and 2) only break

  3. Break as a form goto • A break statement exits a loop before an entry condition fails. • The break statement can also be employed by itself to provide a form of “goto”. The format is: break label:

  4. Example – use break to exit from loop break once it becomes negative

  5. Continue - Explanation • Sometimes it is necessary to exit from the middle of a loop. • Sometimes we want to start over at the top of the loop. • Sometimes we want to leave the loop completely. For Example for (int i = 0; i < length; i++) { if (m[i] % 2 == 0) continue; // process odd elements... } it will process the odd case

  6. Example - continue 1, 3, 5, 7 are missing

  7. Return • It has purpose to exit from the current method • It jumps back to the statement within the calling method that follows the original method call. Example • return expression

  8. Example

  9. Summary • Selection Statements • If and switch • Iteration Statements • While, do-while, for and nested loops • Jump Statements • Break, continue and return
