【加急！送分】java读取txt文件内容，存到二维数组，高手速度来！

[懒得理你1995]

如，

jhert.txt
#dsfdsfd 322324 fdsfsdgwq
# wedsd 211211121 dsggjj
#ewhjdd 3236754 wqewewqa
#lkjhopd 1564987 puiouyiuh
#qooybd 454757
fk1 457845 AL 22321 LJKD
fk2 545785 FH wqqw POIOUO
fk3 457892 BV 23560 HGIHGIU
fk4 895267 KA 21287 HIHHKJU
fk5 784525 QW 54578 TYRTYFS
...........

我想把带#号的忽略掉从fk1往下面读存到数组中 并且每一行只读到 第三个就停止

求大神指教，有相关内容代码直接参考更好，答对我把所有分值奉上给你，非常感谢

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(new File("emplyee.txt"))));
String line = null;
String[][] arr = new String[5][3]; // 此处的5 动态设定吧
int index = 0;
while ((line = br.readLine()) != null) {
	if (line != null && !line.trim().startsWith("#")) {
		String[] strArr = line.split("  ");
		for (int i = 0; i < 3; i++) {
			arr[index][i] = strArr[i];
		}
		index ++;
	}
}
		
for (int i=0; i< arr.length; i++) {
	String[] strArr = arr[i];
	System.out.println(Arrays.toString(strArr));
}

练个手，代码仅供参考

如果我把两个数组的数据都读出来了，怎么样来比较它们之间的内容是否相等呢？

[孙金文]

如果我只是把数值型数据存入到数组中该怎么做呢？谢谢。
