Question

JAVA中怎样接受键盘输入？类似于C语言中的scanf()语句？

Answer 1

JAVA中有Scanner类可以实现这一目的；
示例代码：
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("请输入整数：");
//此处会让你通过控制台输入数字
int num = scanner.nextInt();
System.out.println(num + 1);
}

Answer 2

import java.util.Scanner;
class A{
public static void main(String[] args){
String s=new String();
Scanner c=new Scanner(System.in);
s=c.next();
System.out.print(s);
}
}

Answer 3

import java.io.*;
class ABB
{
public static void main(String[] args) throws IOException
{
InputStreamReader isr=new InputStreamReader(System.in);
char[]a=new char[100];
isr.read(a);
System.out.println(new String(a));
}
}
