猜数字(1.用户猜数字。2.电脑猜数字)

GuessNums.java

public class GuessNums {
  public static void main(String[] args){
		
		int[] nums = new int[100];
		for(int i = 0;i < nums.length;i++){

		System.out.println("请输入您猜的数字(0-99)");
		int guess = input.nextInt();
		
		while(guess >=0 && guess <= 99){
			
			if(guess < nums[index]){
