Java 输入

1.使用Scanner

    使用时需要引入包import java.util.Scanner;首先定义Scanner对象

Scanner sc = new Scanner(System.in);
如果要输入整数，则 int n = sc.nextInt();
String类型的，则String temp = sc.next();

比如：

import java.util.Scanner;

public class Test {
	@SuppressWarnings("resource")
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		System.out.println(scanner.next());
	}
}

2.使用BufferedReader

用前需要引入 import java.io.Reader;

BufferedReader br = new BufferedReader( new InputStreamReader(System.in) );
String input = br.readLine();

比如：

import java.io.*;

public class Test {

	public static void main(String[] args) {
		try {
			BufferedReader br = new BufferedReader(new InputStreamReader(
					System.in));
			System.out.println(br.readLine());
		} catch (IOException e) {

		}
	}
}
