怎么用Java实现拳皇小程序

package helloasd;import java.util.*;
public class hellojava {
		public static void main(String[] args) {
			Scanner input = new Scanner(System.in);
			System.out.print("输入名称: ");
			//用户自己输入名字
			String username = input.next();
			String comname = "阿杰";
			System.out.println(username + "vs" + comname);
			//初始化双方数据
			int hp1 = 100, hp2 = 100;       //双方的HP  
			int attack1 = 0, attack2 = 0;
			
			//使用循环模拟对战过程
			while(hp1 > 0 && hp2 > 0) {
				attack1 = (int)(Math.random() * 1000) % 11 + 5; //双方随机的攻击力（10~15）
				attack2 = (int)(Math.random() * 1000) % 11 + 5; 
				
				//玩家先攻击
				hp2 -= attack1; //玩家攻击，电脑掉血
				System.out.println(comname + ": " + hp2);
				if(attack1 > 0 && attack1 <=5) {
					System.out.println("阿杰被命中攻击！");
				}
				else if(attack1 > 5 && attack1 <=10) {
					System.out.println("阿杰被重重的攻击！");
				}
				else {
					System.out.println("阿杰被致命一击！");
				}
					
				//显示电脑血量
				
				hp1 -= attack2; //电脑攻击，玩家掉血
				System.out.println(username + ": " + hp2);
				//显示玩家血量
				if(attack1 > 0 && attack1 <=5) {
					System.out.println(username + "被" + comname + "侥幸攻击了一下！");
				}
				else if(attack1 > 5 && attack1 <=10) {
					System.out.println(username + "遇到了强烈进攻！");
				}
				else {
					System.out.println(username + "被沉重打击！");
				}
				
				System.out.println("\n");
			}
			//打印结果
			System.out.println("\n");
			System.out.println("KO!");
			System.out.println("玩家姓名\t血量");
			System.out.println(username + "\t" + hp1);
			System.out.println(comname + "\t" + hp2);
