Java Break keyword

     

Java programming involves loops that are widely used by programmers and for handling these loops Java provides keywords such as break and continue respectively. Among these Java keywords break is often used in terminating the loops. ?break? statement inside any loop bring the program control out of the loop. Example below demonstrates the working of break statement.
In the program under some conditions the break statement breaks the label cerebra, due to which the main while loop terminates and the branching statement used in the code is spoken as labeled break statement.
