| 1) Can only appear within a loop or a switch statement. |
| 2) Causes an immediate exit from a loop structure before the test condition is met. Once a break statement is encountered, the loop immediately terminates, skipping any remaining code. |
| For example, |
| for (int x = 0; x < 10; x++) { if (x == 5) break; else System.out.print(" " + x); } |
| will end prematurely when x takes on a value of 5. |
| The output displayed will be: |
| 0 1 2 3 4 |
| 3) It may specify the label of the loop to be abandoned. This makes it possible to abandon a specific loop. |
| For example, |
| outer: for (int i = 1; i <= 5; i++) { for (int j = 5; j >= 1; j--) { if (i == j) break outer; else System.out.println("i = " + i + ", j = " + j); } } |
| will end the outer loop when i equals j. |
| The output displayed will be: |
| i = 1, j = 5 i = 1, j = 4 i = 1, j = 3 i = 1, j = 2 |
| 4) It causes an immediate exit from a switch, skipping any remaining code. |
| For example, if key is a char variable having a value entered by the user, the following statements will display whether they entered an 'A' or a 'B': |
| switch (key) { case 'a': case 'A': System.out.println("You entered an 'A'"); break; case 'b': case 'B': System.out.println("You entered a 'B'"); break; default: System.out.println("You did not enter an 'A' or a 'B'"); break; } |
