Java按行读取文本文件并保存

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.PrintWriter;
public class Accuracy {

//类似于此
public static void main(String[] args) throws Exception {
BufferedReader reader = new BufferedReader(new FileReader("D:\\stanford\\1111111cmn0302.txt"));
String line = reader.readLine();
int k=0;
//fromFile = new BufferedReader(fr);
while(line != null){
String[] list = null;
list = line.split(":");
//                     System.out.println("Success");
//                        System.out.print(list[0]);
File file = new File("D:\\stanford\\"+k+".txt");
file.createNewFile();

PrintWriter output = new PrintWriter(file);
for(int i=0;i<list.length;i++){
output.println(list[i]);
}
output.close();
k++;

}
reader.close();
