从文件中读取数组到内存

public void readDataFromFile(int[][] data, String fileName) {
try {
BufferedReader in = new BufferedReader(new FileReader(new File(
fileName)));
String line;
int row = 0;
while ((line = in.readLine()) != null) {

for (int j = 0; j < temp.length; j++) {
data[row][j] = Integer.parseInt(temp[j]);
}
row++;
}
in.close();
