java Scanner loop input

Purpose of this article

I always forget it, so my memo

I want to input with Scanner in Java and loop the input until the desired numerical value and character string are input. Don't think about exception handling, just a memo for processing.

code

`rupe.java`


Scanner scan = new Scanner(System.in);
while(true){
  int num = scan.nextInt();
  switch(num){
    case //Numerical value you want to enter:
      //Processing content
      break;
    default:
      continue;
  }
  break;
}
