int[][] da = new int[timu][timu]//定义数组时链裂凳未使用数组源缓长度,随机数>3导致数组越界
timu = da.length

这个是更改过的你对棚旅比对比,然后class文件名 不要用中文,用英文,每个单词首字母大写
public static 薯烂Geocache[] createGeocaches(int a) {if(a <= 0) return new Geocache[0]
Random rand = new Random()
Geocache[] result = new Geocache[a]
for(int i = 0 i 模扮< a i++) {
//因为题目没有描述,这里假设x, y是随机整数,Geocache有构造函数(int, int)
int x = rand.nextInt()
int y = rand.nextInt()
result[i] = new Geocache(x, y)
}
数码漏 return result
}
