java使用BufferedReader类

java使用BufferedReader类读取文本文

 

这个例子演示如何使用BufferedReader逐行读取文本文件中的内容。

package cn.outofmemory.example;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class FileUtil {

public void readLinesFromFile(String filename) {

BufferedReader br = null;

try {
//构造BufferedReader对象
br = new BufferedReader(new FileReader(filename));

String line = null;
while ((line = br.readLine()) != null) {

//将文本打印到控制台
System.out.println(line);
}
}
catch (IOException e) {
e.printStackTrace();
}
finally {

//关闭BufferedReader
if (br != null) {
try {
br.close();
}
catch (IOException e) {
e.printStackTrace();
}
}
}

}

public static void main(String[] args) {
FileUtil util = new FileUtil();
util.readLinesFromFile("myfile.txt");
}
}
