package FengZhuang; import java.util.Scanner; class Person { String name; char sex; int age; String IdCard; public void printf() { System.out.print("姓名是:"+name+" "); System.out.print("性别是:"+sex+" "); System.out.print("年龄是:"+age+" "); System.out.println("身份证号码是:"+IdCard); } public Person(String name,char sex,int age,String IdCard) { this.name=name; this.sex=sex; this.age=age; this.IdCard=IdCard; } } public class TestPerson { public static void main(String[] args) { Scanner in= new Scanner(System.in); String name; char sex; int age; String IdCard; System.out.println("请输入姓名,性别,年龄,身份证号码:"); name=in.next(); sex=in.next().charAt(0); age=in.nextInt(); IdCard=in.next(); Person object=new Person(name,sex,age,IdCard); object.printf(); } }
