Switch in Java

In this post, you will learn how to work with switch so that you can use that same knowledge and thus evolve.

• the switch is another way of working with decisions and can only check an equality relationship, ie it cannot use comparison operators;
• the case compares what was defined in itself with the content of the argument that was defined in the switch;
• the default is executed when the content of the argument that was defined in the switch is not found in any case.

package com.caffeinealgorithm.programminginjava;

public class Switch {
  public void Run() {
    char _case = 'D';

    switch (_case) {
      case 'A':
        System.out.println("The case A exists.");
        break;
      case 'B':
        System.out.println("The case B exists.");
        break;
      case 'C':
        System.out.println("The case C exists.");
        break;
      default:
        System.out.printf("The case %c does not exist.", _case);
        break;
    }
  }
}

// The case D does not exist.
