读取文件内容的方法

String path = “D:\test.txt”;          //此处的path包括文件名

String str = “”;

String content = “”;

BufferedReader in = new BufferedReader(new FileReader(path));

while(str = in.readline() != null){

  content = content + str;

}

in.close();

System.out.println(content);

如果文件内容为中文，读取文件内容的方法为：

String str = “”;

String content = “”;

String path = “D:\test.txt”;

File f = new File(f);

InputStreamReader is = new InputStreamReader(new FileInputStream(f),”UTF-8”);

BufferedRead in = new BufferedRead(is);

while(str = in.readline() != null){

  content = content + str;

}

in.close();

System.out.println(content);
