The break Statement

Question 1

Define a break statement !

Answer 1

A break statement in Java is used to exit a loop or a switch statement prematurely. When encountered, it immediately terminates the nearest enclosing loop (like for, while, or do-while) or the switch block, transferring control to the statement following the loop or switch.

Question 1

Give the structure of a break statement !

Answer 1

1. In a Loop:

break; // Exits the nearest enclosing loop

2. With a Label (to exit a specific labeled block):

break labelName; // Exits the labeled block or loop

Question 2

Give all mandatory and optional parts of a break statement !

Answer 2

You can optionally specify a label to exit a specific labeled block or loop. This label must be a valid identifier followed by a colon (:).

Question 3

Give 2 common use cases of a label parameter of a break statement !

Answer 3

Without a label parameter, the break statement will terminate the nearest inner loop it is currently in the process of executing

The optional label parameter allows us to break out of a higher level outer loop

Question 4

Describe the behavior of the loop when using a break statement with a label and without a label and when not using a break statement at all !

Answer 4

Without a break: Both loops execute completely based on their conditions.

With a break (no label): Exits only the nearest loop.

With a break (with label): Exits the specified labeled loop or block.
