一道Java编程题~

public class Person {

private static String name;

private static String sex;

private static int age;

Person(String name, int age) {
this.name = name;
this.age = age;
}

public void print() {
System.out.print("名字:" + name + " 性别:" + sex + " 年龄:" + age + " ");
}
}

public class Student extends Person {

private static String school;

private static String department;

private static String studentno;

Student(String name, int age, String school, String department,
String studentno) {
super(name, age);
this.school = school;
this.department = department;
this.studentno = studentno;
}

public void print() {
super.print();
System.out.println("学校是:" + school + " 系是:" + department + " 学号是:"
+ studentno);
}

}

public classTest{
public static void main(String[] args){
ArrayList list=new ArrayList();
list.add(new Loan());

list.add(new Date());

list.add(new String("我要找个好工作!");

list.add(new JFrame("这个对象不熟悉,不过大概创建都是这样子的");

list.add(new Circle());

loop(list);//调用方法


}

//循环遍历集合的方法

public void loop(List list){
for(Object obj:list){
System.out.println(obj.toString());
}
}

}
//自定义Circle类
class Circle{
public int radius;//半径

public String toString(){
return "我是一个"+radius+"的圆";
}

}
//这可是哥们一个字母一个字母的敲的,认真看看吧

public class Box{

double length;
double width;
double height;
public Box(double length, double width, double height) {

this.length = length;
this.width= width;
this.height= height;
this.sex = sex;
}
public Box() {

}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
public double getLength() {
return length;
}
public void setLength(double length) {
this.length = length;
}
public double getWidth() {
return width;
}
public void setWidth(double width) {
this.width = width;
}
public double getMj() {
return this.getLength()*this.getWidth();
}
public double getTj() {
return this.getLength()*this.getWidth()*this.getHeight();
}
public String toString() {
return "长:"+this.getLength()+"宽:"+this.getWidth()+"高:"+this.getHeight()+"面积:"+this.getMj()+"体积:"+this.getTj();
}

public static void main(String[] args) {
Box box=new Box(12,23,4);
System.out.println(box.toString())
}
}

这么简单,自己做吧,就当锻炼下!
