java按行读取text文件

用java一行一行的读取文件里的内容

文件路径为：

项目/resources/category.txt

项目/src/com/test/file/ReadStringFromFileLineByLine.java

代码为

package com.test.file;

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

public class ReadStringFromFileLineByLine {

public static void main(String[] args) {
// TODO Auto-generated method stub
try {
File file = new File("resources/category.txt");
FileReader fileReader = new FileReader(file);
BufferedReader bufferedReader = new BufferedReader(fileReader);
StringBuffer stringBuffer = new StringBuffer();
String line;
while ((line = bufferedReader.readLine()) != null) {
stringBuffer.append(line);
stringBuffer.append("\n");
}
fileReader.close();
System.out.println("Contents of file:");
System.out.println(stringBuffer.toString());
} catch (IOException e) {
e.printStackTrace();
}
}

}
