[转]Java获得键盘输入的两种方法

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

public class MainClass
{
    public static void method1()
    {
        //使用Scanner
        Scanner scanner=new Scanner(System.in);
        System.out.print("Please input a number:");
        int num=scanner.nextInt();  //获取整数值
        System.out.println("The number you input is:"+num);
        System.out.println("----------------------------");
        System.out.print("Please input some character:");
        String str=scanner.next();  //获取字符串值
        System.out.println("The string you input is:"+str);
    }


    public static void method2()
    {
        //使用BufferedReader
        try
        {
            BufferedReader reader=new BufferedReader(new InputStreamReader(System.in));
            System.out.print("Please input a number:");
            String str=reader.readLine();  //获取字符串
            System.out.println("The number you input is:"+str);
        } catch (IOException e)
        {
            e.printStackTrace();
        }
    }
}
