Break statement in java programming (V38)

Break Statement

The Java break statement is used to exit a loop immediately and transfer the control to the next statement after the loop. It has two main uses: when encountered inside a loop, it instantly terminates the loop, and in a switch statement, it is used to exit a specific case.
