[Code]

• Controller

      @GetMapping("/api/v1/calc")
      public CalcResponse calc(CalcRequest request) {
          return new CalcResponse(request.getNum1(), request.getNum2());
      }
  

• CalcRequest

  public class CalcRequest {
      private int num1;
      private int num2;
  
      public CalcRequest(int num1, int num2) {
          this.num1 = num1;
          this.num2 = num2;
      }
  
      public int getNum1() {
          return num1;
      }
  
      public int getNum2() {
          return num2;
      }
  }
  
  

• CalcResponse

  public class CalcResponse {
      private int add;
      private int minus;
      private int multiply;
  
      public CalcResponse(int num1, int num2) {
          this.add = num1 + num2;
          this.minus = num1 - num2;
          this.multiply = num1 * num2;
      }
  
      public int getAdd() {
          return add;
      }
  
      public int getMinus() {
          return minus;
      }
  
      public int getMultiply() {
          return multiply;
      }
