JAVA继承问题 求代码
第一个:
public class Yaojing {
protected String name;
protected int age;
protected String gender;
public void showBasicInfo() {
System.out.println(toString());
}
public void eatTangSeng() {
System.out.println("吃饱了");
}
@Override
public String toString() {
return "Yaojing [name=" + name + ", age=" + age + ", gender=" + gender + "]";
}
}
第二个类
public class Zhizhujing extends Yaojing {
public void buildNet(){
System.out.println("蜘蛛在织网");
}
}
第三个类
public class Baigujing extends Yaojing {
public void beBeauty(){
System.out.println("白骨精");
}
}
java 类的继承，求大神给代码
public class JIhe {
private String color;
private String dateCreated;
private String filled;
public String getColor() {
return color;
}
public String getDateCreated() {
return dateCreated;
}
public String getFilled() {
return filled;
}
public void setColor(String color) {
this.color = color;
}
public void setFilled(String filled) {
this.filled = filled;
}
@Override
public String toString() {
return "Color:" + this.color +" filled:" + this.filled + "detaCreated:" + dateCreated;
}
}
------------------------------------------------------------------------------------------------------------
public class Circle extends JIhe {
private double radius;
public double getRadius() {
return radius;
}
public void setRadius(double radius) {
this.radius = radius;
}
public double getArea() {
return 3.14 * this.radius * this.radius;
}
public double getPerimeter() {
return 2 * 3.14 * this.radius;
}
public double getDiameter() {
return 2 * this.radius;
}
}
-----------------------------------------------------------------------------------------------------
public class Rectangle extends JIhe {
private double width;
private double height;
public double getWidth() {
return width;
}
public void setWidth(double width) {
this.width = width;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
public double getArea(){
return this.width * this.height;
}
public double getPerimeter(){
return this.width * 2 + this.height * 2;
}
}
——————————————————————————————————————
public class Test {
public static void main(String[] args){
Circle circle = new Circle();
circle.setRadius(1.0);
System.out.println(circle.getArea());
System.out.println(circle.getColor());
System.out.println(circle.getDateCreated());
System.out.println(circle.getDiameter());
System.out.println(circle.getFilled());
System.out.println(circle.getPerimeter());
System.out.println(circle.getRadius());
Rectangle r = new Rectangle();
r.setHeight(2.0);
r.setWidth(4.0);
System.out.println(r.getArea());
System.out.println(r.getColor());
System.out.println(r.getDateCreated());
System.out.println(r.getFilled());
System.out.println(r.getHeight());
System.out.println(r.getPerimeter());
System.out.println(r.getWidth());
}
}
写一个最简单的JAVA继承代码？？谢谢
可运行的：
import java.awt.*;
import java.awt.event.*;
public class BackJFrame extends Frame{
public BackJFrame(){
super("台球");
setSize(300,300);
setBackground(Color.cyan); //背景
setVisible(true);
addWindowListener(new WindowAdapter()
{
public void windowClosing (WindowEvent e)
{System.exit(0);}
} );
}
public static void main(String args[]){
new BackJFrame();
}
}
