Java oop代碼6（原創(chuàng)方法）：5道用上extends繼承，子類，父類的題
//1、父類：交通工具：run方法
子類：公交車(Bus)，自行車(Bike)，飛機(Plane)，地鐵?(Metro)
package a;
public class Student {
public static void main(String[] args) {
feiji f=new feiji("飛機");
f.run();
f.fly();
ditie d=new ditie("地鐵");
d.run();
d.zr();
feiji s=new feiji("公交車");
s.run();
s.zr();
feiji z=new feiji("自行車");
z.run();
z.znpy();
}
}
class jiaotonggongjv{
public String name;
public jiaotonggongjv(String name){
this.name=name;
}//紅色部分是我認為重要或需記憶或不熟或可能會忘的部分
public void run(){
System.out.println("執(zhí)行了"+this.name+"的run方法");
}
public void zr(){
System.out.println("執(zhí)行了"+this.name+"的載人方法");
}
public void fly(){
System.out.println("執(zhí)行了"+this.name+"的飛方法");
}
public void znpy(){
System.out.println("執(zhí)行了"+this.name+"的載女朋友方法");
}
}
class gongjiaoche extends jiaotonggongjv{
public gongjiaoche(String name) {
super(name);
}
}
class zixingche extends jiaotonggongjv{
public zixingche(String name) {
super(name);
}
}
class feiji extends jiaotonggongjv{
/*因為class feiji 繼承了class jiaotonggongjv，所以class?jiaotonggongjv里面的
public String name;
public jiaotonggongjv(String name){
this.name=name;
的代碼作用，class feiji也有了，所以前面可寫出feiji f=new feiji("飛機");，也可寫成
jiaotonggongjv f=new jiaotonggongjv("飛機");讓前面System.out.println("執(zhí)行了"+this.name+"的飛方法");中的this.name可以打印出"飛機"
*/
public feiji(String name) {
super(name);//這里就有可少寫些name代碼的作用了，"飛機"會賦值到name與this.name中
}
}
class ditie extends jiaotonggongjv{
public ditie(String name) {
super(name);
}
}
執(zhí)行效果圖：
//2、父類：人：walk方法
//子類：老師，學生，藍領，白領

e.walk();
e.gzzd();
person s=new person("白領");
s.walk();
s.gzg();
}
}
class person{
public String name;
public person(String name){
this.name=name;
}
public void walk(){
System.out.println("執(zhí)行了"+this.name+"的walk方法");
}
public void say(){
System.out.println("會說");
}
public void play(){
System.out.println("會玩");
}
public void gzzd(){
System.out.println("工資中等");
}
public void gzg(){
System.out.println("工資高");
}
}
class gongjiaoche extends person{
public gongjiaoche(String name) {

ditie d=new ditie("數(shù)學");
d.exam();
d.zr();
feiji s=new feiji("英語");
s.exam();
s.zx();
}
}
class kecheng{
public String name;
public kecheng(String name){
this.name=name;
}
public void exam(){
System.out.println("執(zhí)行了"+this.name+"的exam方法");
}
public void zr(){
System.out.println("執(zhí)行了"+this.name+"的變得聰明的方法");
}
public void fly(){
System.out.println("執(zhí)行了"+this.name+"的變得有涵養(yǎng)的方法");
}
public void zx(){
System.out.println("執(zhí)行了"+this.name+"的變得自信的方法");
}
}
class gongjiaoche extends kecheng{
public gongjiaoche(String name) {
super(name);
}
}
class zixingche extends kecheng{
public zixingche(String name) {
super(name);
}
}
class feiji extends kecheng{

}
class ditie extends kecheng{
public ditie(String name) {
super(name);
}
}
4、父類：形狀：pait方法
子類：三角形，正方形，圓形，五角星
package a;
public class Student {
public static void main(String[] args) {
sjx f=new sjx("三角形");/*這里sjx（子類名）換為person（父類名），雖然可少寫些extends部分，但就沒太多意義了，只是單純的方法調用了，因為這題是為了多練熟extends部分，所以不換為person，這里寫了相應的extends部分，才可xie相應的 子類名? 名=new??子類名（"? ? ?"）*/
f.pait();
f.stb();
zfx d=new zfx("正方形");
d.pait();
d.sitb();
yx e=new yx("圓形");
e.pait();
e.ka();
wjx s=new wjx("五角星");
s.pait();
s.wgj();
}
}

public String name;
public person(String name){
this.name=name;

}
public void ka(){
System.out.println("圓圓的很可愛，讓人有視覺享受");
}
}
class sjx extends person{
public sjx (String name) {
super(name);

}
}
5、父類：英雄：cast方法

public class Student {
public static void main(String[] args) {
