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();
                 }
         }
 }
