建立一个Person类和学生类_创建一个person类

    class Person{
	String name;
	String addr;
	char sex;
	int age;
	public Person(String name,String addr,char sex,int age){
		System.out.println("姓名："+name+"  地址："+addr+"  性别："+sex+"  年龄："+age);
		this.name=name;
		this.addr=addr;
		this.sex=sex;
		this.age=age;
	}
	public Person(String name,char sex){
		System.out.println("姓名："+name+"  性别："+sex);
		this.name=name;
		this.sex=sex;
	}
	public Person(){
	}
	public void getinfo(){
		System.out.println("姓名："+name+"  地址："+addr+"  性别："+sex+"  年龄："+age);
	}
}
class Student extends Person{
	float math;
	float english;
	public Student(String name,String addr,char sex,int age,float math,float english){
		super(name,addr,sex,age);
		this.math=math;
		this.english=english;
	}
	public Student(String name,char sex){
		System.out.println("姓名："+name+"  性别："+sex);
	}
	public Student(){
		
	}
	public void getinfo(){
		System.out.println("姓名："+name+"  地址："+addr+"  性别："+sex+"  年龄："+age+"  数学成绩："+math+"  英语成绩："+english);
	}
}
public class t63 {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Person p=new Person("里西斯","上海",'男',34);
		Student s1=new Student("赵晓赵",'女');
		Student s2=new Student("赵小赵","河北",'女',18,100,100);
		Student s3=new Student("赵小小赵","云南",'女',17,100,100);
		Student s4=new Student("赵晓小小赵","北京",'女',16,100,100);
		Student s5=new Student("赵小小小赵","桂林",'女',13,100,100);
