自定义函数sdwu_get_content()，分别读取data文件夹下的neg和pos文件夹中的文件。

帮我检查代码：package cn.sdwu; import java.util.Random; import java.util.Scanner; public class text1 { public static void main(String[] args) { int computer,win=0,lose=0; String player; Random r=new Random(); Scanner sc=new Scanner(System.in); System.out.println("请输入【棒/老虎/鸡/虫】："); while(true) { computer=r.nextInt(4)+1; System.out.print("你出："); player=sc.next(); switch(computer) { case 1: System.out.println("计算机出：棒"); case 2: System.out.println("计算机出：老虎"); case 3: System.out.println("计算机出：鸡"); case 4: System.out.println("计算机出：虫"); } switch(player) { case "棒": switch(computer) { case 1: case 3: System.out.println("平局！！！"); break; case 2: System.out.println("你赢了！！！"); win++; break; case 4: System.out.println("你输了！！！"); lose++; break; } break; case "老虎": switch(computer) { case 2: case 4: System.out.println("平局！！！"); break; case 3: System.out.println("你赢了！！！"); win++; break; case 1: System.out.println("你输了！！！"); lose++; break; } break; case "鸡": switch(computer) { case 1: case 3: System.out.println("平局！！！"); break; case 4: System.out.println("你赢了！！！"); win++; break; case 2: System.out.println("你输了！！！"); lose++; break; } break; case "虫": switch(computer) { case 2: case 4: System.out.println("平局！！！"); break; case 1: System.out.println("你赢了！！！"); win++; break; case 3: System.out.println("你输了！！！"); lose++; break; } break; default: System.out.println("请输入【棒/老虎/鸡/虫】："); break; if(win==2 && lose<2) { System.out.println("你已赢两局，恭喜你大获全胜！！！"); break; } else if(lose==2 && win<2) { System.out.println("很遗憾，你已输两局，被淘汰出局！！！"); break; } } } } } ​
