從標準輸入中讀取一個人的姓氏，他們的名字和他們的家庭位置 - 每個人都在一條獨立的線路上

Question

嗨，我們共同的初學者，當我們做java的時候在課堂上迷失了這是我的代碼，但它不會閱讀者名姓氏和位置

import java.util.Scanner; 

public class lab1 { 

    public static void main(String[] args) { 

     String firstName,lastName,location; 


     //Create scanner to obtain user input 
     Scanner scanner1 = new Scanner(System.in); 

     //obtain user input 
     System.out.println("Enter your first name: "); 
     firstName = scanner1.nextLine(); 

     System.out.println("Enter your last name: "); 
     lastName = scanner1.nextLine(); 

     System.out.println("Enter your location: "); 
     lastName = scanner1.nextLine(); 

     //output information 
     System.out.print("Hello + firstName + " + "lastName + "location) 
    } 
} 

Answer 1

它確實有輕微的修改，對於位置你又回到分配給lastName的

System.out.println("Enter your location: "); 
lastName = scanner1.nextLine(); 

稍作修改後，我們可以看到下面的控制檯輸出

public static void main(String[] args) { 

     String firstName,lastName,location; 


     //Create scanner to obtain user input 
     Scanner scanner1 = new Scanner(System.in); 

     //obtain user input 
     System.out.println("Enter your first name: "); 
     firstName = scanner1.nextLine(); 

     System.out.println("Enter your last name: "); 
     lastName = scanner1.nextLine(); 

     System.out.println("Enter your location: "); 
     location = scanner1.nextLine(); 

     System.out.println(firstName + " " + lastName + " " + location); 

    }
