![]() ![]() 'Break' is designed for use inside loops (for, while, do-while, enhanced for and switch). If you remove the 'break' command from your code and then test the code, you should find that the code works exactly the same without a 'break' command as with one. There's no need to preemptively save the result in a variable either. The 'break' command does not work within an 'if' statement. If omitted, all the cases after the matching case will also be executed. It is used at the end of every case block so that when the matching case is executed, the program control comes out of the loop. Without having to worry about the function being re-evaluated for every case. The break keyword is used in the switch case to break out of the switch when encountered. I think this fact needs a little bit more attention, so here's an example: Based on the evaluation of a condition, a statement or a sequence of statements is executed. Decision-making statements enable us to change the flow of the program. The difference between a series of if statements and the switch statement is that the expression you're comparing with, is evaluated only once in a switch statement. The decision-making or control statements supported by Java are as follows: if statement. to the next chapter - that inside a subroutine, the break statement is sometimes. This is listed in the documentation above, but it's a bit tucked away between the paragraphs. THE SECOND BRANCHING STATEMENT in Java is the switch statement, which is. The break statements are necessary because without them, statements in switch blocks fall through: All statements after the matching case label are executed in sequence, regardless of the expression of subsequent case labels, until a break statement is encountered.
