java - 打印、阅读、运算符(operator)

Question

我是 java 的新手，我应该得到如下输出:

输入您的名字:John

Hi, "John"
The name of this exercise is 'Modifying printing'.
Tabulator, line change and quotations have already been used in this exercise.
Backward slash (\) is also usable in printing.

练习结束

但我无法在 "" 中获取姓名部分，John。请任何人帮助我。我的代码如下所示:

---

import java.util.Scanner;
public class apples {
public static void main(String[] args) {
String s;
String m;
Scanner reader= new Scanner(System.in);
System.out.print("Type in your first name: ");
s= reader.nextLine();
m="Forward slash (\\) is also usable in printing.";
System.out.println();
System.out.println();
System.out.println("Hi, "+s);
System.out.println("\tThe name of this exercise is 'Modifying printing'.");
System.out.println("\tTabulator, line change and quotations have already been used in   this exercise.");
System.out.println("\t"+m);
System.out.println();
System.out.println();
System.out.println("\t\t*** End of exercise ***");
}
}

Answer 1

 System.out.println("Hi, \"" + s + "\"");

其中\用于转义后面的 ".

在您喜欢的搜索引擎中搜索“java 中的转义字符”。

祝您开始使用 Java 愉快!
