The looping does not stop after a true answer, why?

Question

"Ok, so you want to keep looping as long as the user didn't enter 1, 2, or 0, right?"
Answer: Yes that's it.
boolean repeat = false ;
do {
System.out.print(" Option 1  \nOption 2 \nOption 0" );
   int x = Integer.parseInt(br.readLine().trim());
      switch(x) {
   case 1 : System.out...etc.("test");
   case 2 : System.out...etc.("test");
   case 0 : System.out...etc.("test");
  default :  repeat = true; 
} while( repeat == true) ; Steals repeating even if u give a true answer( 1 2 or 0)
Help! :P

Answer 1

If you go through the loop once with something other than 0, 1, 2, then repeat will be set to true, and it will never have the possibility to be set to false again.
Each case should also set repeat to false.
You should NOT initialize repeat to false at declaration. That way, if you miss one of the repeat = false; settings in the cases, the compiler will give you an error. As you have it now, the same logic error is still present, but the compiler can't detect it.
