unable to change the TextArea.background !

Code:

---

import javax.swing.*;
import javax.swing.JPanel;
import javax.swing.UIManager;
import javax.swing.plaf.ColorUIResource;
import java.awt.Color;

public class EasyToolTip extends JPanel {

    JTextArea t = new JTextArea(10, 10);

    EasyToolTip() {
        UIManager.put("ToolTip.background", new ColorUIResource(Color.CYAN));
        UIManager.put("TextArea.background", new ColorUIResource(25, 25, 25));
        setToolTipText("This is also a way to change the color of the tooltip in your application!");
        add(t);
    }

    public static void main(String[] args) {
        javax.swing.JFrame frame = new javax.swing.JFrame("EasyToolTip");
        frame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
        frame.add(new EasyToolTip());
        frame.setSize(1280, 770);
        frame.setVisible(true);
    }
}

The order in which code gets called is what matters here since you are creating your JTextArea before the UIManager has had a chance to change the default background. Change that and your program will change its display:

Code:

---

import javax.swing.*;
import javax.swing.JPanel;
import javax.swing.UIManager;
import javax.swing.plaf.ColorUIResource;
import java.awt.Color;

public class EasyToolTip extends JPanel {

  JTextArea t; // = new JTextArea(10, 10);

  EasyToolTip() {
    UIManager.put("ToolTip.background", new ColorUIResource(Color.CYAN));
    UIManager.put("TextArea.background", new ColorUIResource(25, 25, 25));
    t = new JTextArea(10, 10);
    setToolTipText("This is also a way to change the color of the tooltip in your application!");
    add(t);
  }

  public static void main(String[] args) {
    javax.swing.JFrame frame = new javax.swing.JFrame("EasyToolTip");
    frame.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
    frame.add(new EasyToolTip());
    frame.setSize(1280, 770);
    frame.setVisible(true);
  }
}
