A return within any loop or block will of course also immediately terminate that loop/block. return is used the terminate a method (and possibly return a value). Break and return in Javaīreak is used to immediately terminate a for loop, a while loop or a switch statement. If the Boolean expression is true, the control jumps back up to do statement, and the statements in the loop execute again. Another way would be to reset the variable each time it is necessary.ĭo while (Boolean_expression) Notice that the Boolean expression appears at the end of the loop, so the statements in the loop execute once before the Boolean is tested. It is a good practice to only define variables in the scope they actually have a meaning (in this case in the while-loop). This means, every time the while-loop performs one iteration, variable is newly created. Click the following links to check their detail.

Be able to print a line that says Command not recognized (I can do that part), and then return to the top of the loop so they can try again (don't know how to do this part).Ī loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages − Java programming language provides the following types of loop to handle looping requirements. We do this with the help of break and continue statements respectively.Īs you can see, if the player doesn't input any of the options, the loop terminates, and in this case the enemy gets 2 free attacks. In Java, we can jump out of a loop or jump to the starting condition of a loop whenever we want.
You can't restart an if statement, but you can modify your loop control variable in the for loop. TL DR It sounds like you want a while loop or possibly a recursive function.
