How to repeat an if or switch statement if something out of option is entered?

Question

This will mostly get duplicated but I sincerely don\'t know how to search this question since it is too long and complicated. Sorry in advance!

Back to the problem,

Answer 1

So if you enter defend or attack, it will not ask again, otherwise repeat the process. Try this:

    do{
    String input = scan.nextLine();
    switch( input) {
        case "attack":
           System.out.println( "You attacked the enemy!");
           break;

        case "defend":
           System.out.println( "You blocked the enemy!");
           break;

        default:
           System.out.println( "This is not an option!");
           // somehow repeat the process until one of the case options are 
           // entered.
    }
}while(!"attack".equalsIgnoreCase(input) || !"defend".equalsIgnoreCase(input))
