为什么我的 if else 语句不能按预期工作？ 输入问题

Question

Why can my code not go on the process of if else statement? it's inputting 3 times and I need only 1 input.

I can't see what's wrong with this code, please help me

import java.util.Scanner;

public class Main{

public static void main(String[] args) {
    
        Scanner input = new Scanner(System.in);

        System.out.print("Employee Full name:  ");
        String fn = input.nextLine();
        System.out.print("Employee Number:  ");
        int en = input.nextInt();
        System.out.print("Enter the current monthly salary:  ");
        int ms = input.nextInt();
        System.out.print("Enter the performance rating:  ");
        double pr = input.nextDouble();
        double raise = input.nextDouble();
        double nms = input.nextDouble();
        
        {   
        if(pr == 1){
            System.out.println("EXCELLENT!!");
            raise = ms * .06;
        }
        else if(pr == 2){
            System.out.println("Good!");
            raise = ms * .04;
        }
        else if(pr == 3){
            System.out.println("poor.");
            raise = ms * .015;
        }
        else{
            System.out.println("ERROR!!!");
        }
        nms = ms + raise;

        System.out.println(fn);
        System.out.println(en);
        System.out.println(raise);
        System.out.println(nms);
        }
    }   
}

OUTPUT:

That's the output

I really don't know what is wrong

Answer 1

Scanner(System.in) uses the buffer to store the input value(s) from begin to the end marked by ENTER (\r\n). As long as you use

scaner.nextLine(); // read the whole line and remove ENTER

But if you do

int ms = input.nextInt();
 System.out.print("Enter the performance rating:  ");
 double pr = input.nextDouble();

The pr = input.nextDouble() gets the white space ENTER and that is invalid. You have 2 choices: either

int ms = Integer.parseInt(input.nextLine());

or

int ms = input.nextInt();
imput.netxLine(); // jump over ENTER
