请用java编写一个小程序，要求如下：

题目：请选择C++或JAVAV编写一个小程序，比较两个文档的相似性。具体要求如下：~

作业请自己完成，不然没分喔同学

abstract class VirtualLife{
int lifeValue;
int attackPowe;
int describe;
public abstract void physicalAttack();
}
abstract class VirtualHero extends VirtualLife{
int defense;
int armor;
}
interface ISkill{
void skillFirst();
void skillSecond();
void skillThird();
void skillFourth();
}
class Ezreal extends VirtualHero implements ISkill{
String hero ="Ezreal";
public void physicalAttack() {
System.out.println(hero+"物理攻击为"+attackPowe);
}
public void skillFirst() {
System.out.println(hero+"使用了技能"+1);
}
public void skillSecond() {
System.out.println(hero+"使用了技能"+2);
}
public void skillThird() {
System.out.println(hero+"使用了技能"+3);
}
public void skillFourth() {
System.out.println(hero+"使用了技能"+4);
}
}
class Annie extends VirtualHero implements ISkill{
String hero ="Annie";
public void physicalAttack() {
System.out.println(hero+"物理攻击为"+attackPowe);
}
public void skillFirst() {
System.out.println(hero+"使用了技能"+1);
}
public void skillSecond() {
System.out.println(hero+"使用了技能"+2);
}
public void skillThird() {
System.out.println(hero+"使用了技能"+3);
}
public void skillFourth() {
System.out.println(hero+"使用了技能"+4);
}
}
class Soliders extends VirtualLife{
public void physicalAttack() {
System.out.println("我是小兵，我的攻击力为"+attackPowe);
}
}
public class Test {
public static void main(String[] args){
Ezreal ezreal=new Ezreal();
ezreal.attackPowe=10;
ezreal.physicalAttack();
Annie annie=new Annie();
annie.attackPowe=20;
annie.physicalAttack();
Soliders solider=new Soliders();
solider.attackPowe=5;
solider.physicalAttack();
}
}

很简单的

Scanner na=new Scanner(System.in);

String s="a";

System.out.println("请写出"+s+"的大写");

if(na.nextLine().equals(s.toUpperCase())){///判断输入的值和S的值大写是否相等

System.out.println("你真棒！");

}else{

System.out.println("继续努力吧！");

}

import java.io.IOException;

public class test {

public static void main(String[] args) throws IOException {

System.out.println("a");

char i= 0;
i=(char)System.in.read();

if((String.valueOf(i)).equals(("a".toUpperCase())))
System.out.println("你真棒！");
else
System.out.println("继续努力！");
}
}

char ch='a';
ch=(char)(ch-32);
System.out.println(ch);
判断自己写
