- 1、用java写一个程序,用变量保存自己的个人信息,并且输出
- 2、Java实现简单个人信息录入
- 3、编写一个简单的java程序显示个人信息:姓名,性别,出生年月,爱好?
import java.util.Scanner;
public class 个人信息
{
public static void main(String[] args)
{
System.out.println(“\n\t\t==========简单的个人信息录入==========\n”);
init();
}//初始化!
private static void init()
{
/*int a1 = 073;
long b1 = 0xa38f;
System.out.println(a1+”…..”+b1);*/
for (; ; )
{
System.out.println(“请输入姓名:”);
String a=Input.getName();
System.out.println(“请输入年龄:”);
int b=Input.getAge();
System.out.println(“请输入学历:”);
String c=Input.getEducation();
System.out.println(“你输入的信息^_^\t名字:”+a+” 年龄:”+b+” 学历:”+c+”\n”);
}
}
}
class Input
{
private static Scanner sc=new Scanner(System.in);
private Input(){}
static String getName()
{
String name=sc.next();
return name;
}
static int getAge()
{
int age=sc.nextInt();
return age;
}
static String getEducation()
{
String education=sc.next();
return education;
}
}
数据库就要你自己建了.
