Condition in Java but always skip the rest of if and if else [duplicate]

1. This is basic calculator.

2. I love programming

3. All of if and if else will be skipped downward, If I select + operator, it doesn't follow the if + statement.

   Scanner Input = new Scanner(System.in);
   
   try {
       System.out.print("Enter a number: ");
       int num1 = Input.nextInt();
   
       System.out.print("Enter an operator: ");
       String operator = Input.nextLine();
       Input.nextLine();
       String FinalOp = operator;
   
       System.out.print("Enter a second number: ");
       int num2 = Input.nextInt();
       // this part of decision, it doesn't work.
       if ("+".equals(FinalOp)) {
           System.out.println("Your result is " + (num1 + num2));
       } else if ("-".equals(FinalOp)) {
           System.out.println("Your result is " + (num1 - num2));
       } else if ("x".equals(FinalOp)) {
           System.out.println("Your result is " + (num1 * num2));
       } else if (":".equals(FinalOp)) {
           System.out.println("Your result is " + (num1 / num2));
       } else {
           System.out.println("Your answer is not valid");
       }
   }
   catch(InputMismatchException e) {
       System.out.println("similar to try and except in Python");
   }
