System.out.println to text file

Question

I was searching a way to get System.out.println texts and save them on a .txt file, for example:

    System.out.println(\"Java vendor: \" + Syst         


        

Answer 1

You can do,

PrintStream fileStream = new PrintStream("filename.txt");
System.setOut(fileStream);

Then any println statement will go into the file.

Answer 2

First you need to declare a String text that contains your message you want to output:

String text = "Java vendor: " + System.getProperty("java.vendor");

Then you can use try-with-resources statement (since JDK 7) which will automatically close your PrintWriter, when all the output done:

try(PrintWriter out = new PrintWriter("texts.txt")  ){
    out.println(text);
}

Answer 3

You are using standard System output stream which writes to console.You need to use PrintStream class,create a file and write to it.Example is below :
