java键盘输入的2种用法，平时用得比较少，直接上代码

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;

public class InputTest {
	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String str = null;
		
		System.out.println("请输入:");
		str = br.readLine();
		System.out.println("你输入的是 :" + str);

		Scanner sc = new Scanner(System.in);
		
		System.out.println("请输入你的姓名：");
		String name = sc.nextLine();
		System.out.println("请输入你的年龄：");

		int age = sc.nextInt();
		System.out.println("请输入你的身高：");
		float salary = sc.nextFloat();

		System.out.println("你的信息如下：");
		System.out.println("姓名：" + name + "\n" + "年龄：" + age + "\n" + "身高：" + salary);
		
		//关闭资源
		sc.close();
	}
}
