The switch judgment statement in Java typically USES an instance

The following is an example of a typical switch syntax.

import java.util.Scanner; 
public class JudgeMonth { 
  public static void main(String[] arg){ 
    Scanner scan = new Scanner(System.in); 
    System.out.println(" Please enter month :"); 
    int month = scan.nextInt(); 
    switch(month){ 
      case 12: 
      case 1: 
      case 2: 
        System.out.println(" In the winter "); 
        break; 
      case 3: 
      case 4: 
      case 5: 
        System.out.println(" In the spring "); 
        break; 
      case 6: 
      case 7: 
      case 8: 
        System.out.println(" In the summer "); 
        break; 
      case 9: 
      case 10: 
      case 11: 
        System.out.println(" In the fall ");   
        break; 
      default: 
        System.out.println(" No month! Please re-enter ."); 
    } 
  } 
}
