How to add a new line when writing to a text file?

Question

So my code basically asks the user to enter an integer and that integer is saved into a file by writing it. However, when I want to add another integer, it just replaces the previous integer entered. How do I add the new integer in file without replacing the previous one?

public static void main(String[] args) throws IOException {
    File file = new File("Text.txt");
    FileWriter fw = new FileWriter(file);
    PrintWriter writer = new PrintWriter(fw);

    int steps = Integer.parseInt(JOptionPane.showInputDialog("How many steps"));

    writer.println(steps);

    writer.close();

    }

您必须通过发送true参数以“追加”模式初始化FileWriter对象。

FileWriter fw = new FileWriter(file , true)
