java使用BufferedReader類讀取文本文

 

這個例子演示如何使用BufferedReader逐行讀取文本文件中的內容。

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 {
//構造BufferedReader對象
br = new BufferedReader(new FileReader(filename));

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

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

//關閉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");
}
}
