System.out.print() 不适用于我的代码还是我的编译器？

问题描述

我正在为我的编译器使用 gosApache NetBeans，这就是我的代码

package com.mycompany.mavenproject4;
import java.util.*;

public class MyZodiac {
    public static void main(String[] args) {
        Scanner zodiac = new Scanner(system.in);     
                
        System.out.println("Chinese Zodiac Sign");
        System.out.print("Enter your Name: ");
        System.out.print("");
        String name = zodiac.next();
        zodiac.nextLine();
       
        System.out.print("Enter your year of birth: ");
        int year = zodiac.nextInt(); 
}}

然后当我运行这段代码时，它变成了这样

    Chinese Zodiac Sign
    <user input name>
    <user input year>
    Enter your Name: Enter your year of birth:

我想要的是

Chinese Zodiac Sign
Enter your name: <user input>
Enter your year of birth:<user input>

解决方法

System.out.println 包含一个换行符，它会导致对缓冲输出进行隐式刷新（如 System.out）。您可以明确flush。但是打印 "" 没有任何作用。总之，改变

System.out.print("Enter your Name: ");
System.out.print("");
String name = zodiac.next();
zodiac.nextLine();

System.out.print("Enter your year of birth: ");

到

System.out.print("Enter your Name: ");
System.out.flush();
String name = zodiac.next();
zodiac.nextLine();

System.out.print("Enter your year of birth: ");
System.out.flush();
