...........
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
------解决方案--------------------
public static void main(String[] args) {
try {
String encoding = "GBK";
File file = new File("jhert.txt ");
if (file.isFile() && file.exists()) { // 判断文件是否存在
InputStreamReader read = new InputStreamReader(
new FileInputStream(file), encoding);// 考虑到编码格式
BufferedReader bufferedReader = new BufferedReader(read);
String lineTxt = null;
while ((lineTxt = bufferedReader.readLine()) != null) {
if ('#'==lineTxt.charAt(0)) {
continue;
}else{
String[] arr=lineTxt.split(" ");
for (int j = 0; j < arr.length; j++) {
System.out.print(arr[j] + " ");
}
System.out.println();
}
}
read.close();
} else {
System.out.println("找不到指定的文件");
}
} catch (Exception e) {
System.out.println("读取文件内容出错");
e.printStackTrace();
}
