    Lightbulb TxT file - write in the next line

    Hello guys I need a little help(I think). So i start work with TxT files. And i need know how to write text in the next line if file exist. My code just last text replace new.. Here code :
    Main :
     package YoYo;
    import java.util.Scanner;
     
    public class Main {
    	static String atsakymas;
    	static String FileName;
     
     
     
    	static Scanner kl = new Scanner(System.in);
    	static Scanner kl2 = new Scanner(System.in);
     
    	static Creating create = new Creating();
    	public static void main(String[]args) {
     
    		String irasyti = grazina();
     
    		System.out.println("Please enter file name");
    		FileName = kl.nextLine();
    		create.createFile(FileName,irasyti);
    		create.closeFile();
     
     
     
    		}
     
    	static String grazina() {
    		String irasyti = null;
    		System.out.println("Are you want write something in file?");
    		atsakymas = kl2.nextLine();
    		if (atsakymas.equals("Yes")) {
    			System.out.println("What you want write?");
    			irasyti = kl.nextLine();
    			System.out.println(irasyti);
     
    		}
    		return irasyti;
     
    	}
     
    }

    Creating:
     
    package YoYo;
     
    import java.io.FileNotFoundException;
    import java.io.PrintWriter;
    import java.io.UnsupportedEncodingException;
    import java.util.Formatter;
     
    public class Creating {
     
    	PrintWriter x;
    	String file;
    	String WhatWrite;
     
    	public void createFile(String filename, String writing) {
    		file = filename;
    		WhatWrite = writing;
    		try {
     
    			x = new PrintWriter(file);
    			x.println(WhatWrite);
     
     
    		} catch(Exception e) {
    			System.out.println("Error");
    		}
     
    	}
     
     
     
    	public void closeFile() {
    		x.close();
    	}
     
     
     
     
     
     
    }

    If you want to "append" to the content of an already existing file:

    new PrintWriter(new FileOutputStream(file, true));

    In FileOutputStream constructor, "true" means "open in append mode".
