CodePudding user response:

//read TXT file content
Public static String txt2String () {
String filePath="D:/test. TXT";
The File File=new File (filePath);
The StringBuilder result=new StringBuilder ();
Try {
BufferedReader br=new BufferedReader (new FileReader (file));//construct a BufferedReader class to read the file
String s=null;
While ((s=br. ReadLine ())!=null) {//use the readLine method, a read a line of
Result. Append (System. LineSeparator () + s);
}
Br. The close ();
} the catch (Exception e) {
e.printStackTrace();
}
Return the result. The toString ();
}
