How do you get the text in system.output.println?

Question

On the output part of my IDE (where all the system.out.println textx appear), I have several lines of text. I want to get them and save them to a text file. What would be the possible code for this?

Well somewhere in your code you must have defined the `System.out.println` arguments. take them? — PKlumpp, Jun 13 '14 at 07:22

use System#setOut() to redirect output to FileOutputStream to redirect System output to file

 // for restore purpose 
 PrintStream oldOutStream = System.out;

 PrintStream outFile = new PrintStream(
            new FileOutputStream("/path/to/file.txt", true));
 System.setOut(outFile);

 System.out.println("this will goto file");

I assume you know about logging framework and you are not trying to use this for logging something

Yo can replce all sop with fileoutput strem and write everything in file

if you want to write log then you can use log4j

String content = "This is the content to write into file";

File file = new File("filename.txt");

// if file doesnt exists, then create it
if (!file.exists()) {
    file.createNewFile();
}

FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(content);
bw.close();
