Java【第二课 扫描仪 & 布尔数据类型】

import java.util.Scanner;    //导入扫描仪
public class demo{
   public static void main(String[] args){
     
      Scanner data = new Scanner(System.in);   //扫描仪句柄
      System.out.println("请输入名字:");
      String name = data.next();              //接收字符串
      System.out.println("请输入年龄:");
      int age = data.nextInt();               //接收整型
      System.out.println("请输入版本,例如8.0:");
      double version = data.nextDouble();    //接收浮点型

      System.out.println("你的名字:" + name);
      System.out.println("你的年龄:" + age);
      System.out.println("你的版本:" + version);
   }
}

public class demo{
   public static void main(String[] args){
     
       int a = 23;   
       int b = 25;
       boolean flag;  //定义布尔型
       flag = a==b;
       System.out.println(a == b);
       System.out.println(flag);
   }
