You have already seen the break statement used in an earlier chapter of this tutorial. Java break statement is seen inside the loop, the loop is immediately terminated, and the program control resumes at the next statement, which is following the loop. It can be used to exit from a loop. Terminating the loop is advisable rather than waiting for your loop to finish. Then, the control of the program jumps to the statement after the labeled statement. Note: The break statement is also used to terminate cases inside the switch statement. Syntax is pretty much simple.
