FileWriter fw = new FileWriter("/home/joci/Joci test.txt");
fw.write(text);
fw.close();

}catch(IOException e ){
System.out.println("Something went wrong ");

}

Answer 1

Initially, I your problem is that

"/home/joci/Joci test.txt"

does not denote a valid file name under Linux; so you simply drop that space; or replace it with _ or - for example. Or use \\ to escape that space.

But I just tried:

import java.io.*;

public class Test {
  public static void main(String[] args) {
  try{            
    String text = "this is just a test ";
    FileWriter fw = new FileWriter("/home/myhome/tmp/out 21.txt");
    fw.write(text);
    fw.close();
  }catch(IOException e ){
  System.out.println("Something went wrong ");
  }  
}

}

And that just worked fine. So there must be something else in your setup that causes this problem!

Besides: the ~ character is a functionality of the shell of your Linux. The JVM does not know that this character means "home"; thus you should simply not at all use it within your java source code!
