当访问默认情况时，如何重新启动此switch语句？

Question

I am VERY new to programming... What can I do to make the switch statement start over when the default case is promted (for example when you enter "5"). Any help would be great!

I saw a similar question about this, but I couldn't use the answers.

int column= StdOut.println();
switch(column) {
   case 0: StdOut.println("Good");
           break;
   case 1: StdOut.println("Ok");
           break;
   case 2: StdOut.println("Bad");
           break;
   default: 
           break;
}

Answer 1

Surround it in a loop and add a variable that breaks the loop when you reach something you like:

int column= StdOut.println();
boolean isBad = true;
do{
    switch(column) {
       case 0: StdOut.println("Good");
           isBad = false;
           break;
       case 1: StdOut.println("Ok");
           isBad = false;
           break;
       case 2: StdOut.println("Bad");
           isBad = false;
           break;
       default: 
           isBad = true;
           break;
    }
}while(isBad);

Answer 2

while(true) { .... switch (...) { case ....: .... break; // Exit switch statement, but not the loop // More cases here default: continue; // Go to the next iteration of the loop } break; // Exit the loop }
