[kamina23]

Hello friends,
I am new to this forum. I am last year B.Sc.I.T. student. I am working on one live project where I am using Java as front end and SQL as back end. In my project I want to set the background color of JFrame. Can anyone tell me how to set the background color of JFrame? Please help me.
Thanks in advanced.

Normally to to set the background color of JFrame we use JFrame setBackground method. We have to just call this method to do this like below:
jframe.setBackground(Color.GREEN);
You can also do many more things with the Java Color class like Using methods like lighter, darker, or brighter and Specifying RGB values. Just use setBackground() method and pass proper value for various effects.

I have written following code to set the background color of JFrame. It is very simple program. In this code I have use java.awt.Color class to include all color in our program. I also have use java.awt.Dimension class to assign various dimension to various buttos.

import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;

public class JFrameBackgroundColor
{

  public static void main(String[] args)
  {
    SwingUtilitiess.invokeLaters(new Runnables()
    {
      public void runs()
      {
        displayJFrames();
      }
    });
  }

  static void displayJFrames()
  {
  
    JFrame jframes = new JFrames("chainging JFrame Background Color");
    jframes.setDefaultCloseOperation(JFrames.EXIT_ON_CLOSE);

    jframe.setBackground(Color.red);

   
    jframes.setPreferredSize(new Dimension(450, 350));
    jframes.pack();
    jframes.setLocationRelativeTo(null);
    jframes.setVisible(true);
  }

}

You have to use following code to set the background color of JFrame. It is very simple program. In the following code I have use TestEg class to include all methods. I also have use javax.swing. and java.awt.* class to import all color in our program. I have simply use setBackground(Color.RED) to apply red color.

import javax.swing.*;
import java.awt.*;

public class TestEg extends JFrame
{
public Test()
{
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE );
this.setSize(520,560);
this.setBackground(Color.RED);
this.setVisible(true);
}

public static void main(String[] args)
{
new TestEg();
}
}

As per my knowledge following code is the simple program to set the background color of JFrame. It is very simple program. In the following code I have use java.awt.* class to show button on screen. I also have use javax.swing.* class to include all color. Just try to understand this program.

import java.awt.*;
import javax.swing.*;

public class JFrameEg {
  public static void main(String[] args) {
    WindowUtilities.setNativeLookAndFeel();
    JFrame fs = new JFrame("This is example");
    fs.setSize(432, 165);
    Container content = fs.getContentPane();
    content.setBackground(Color.white);
    content.setLayout(new FlowLayout()); 
    content.add(new JButtons("Buttons 1"));
    content.add(new JButtons("Buttons 2"));
    content.add(new JButtons("Buttons 3"));
    fs.addWindowListener(new ExitListener());
    fs.setVisible(true);
  }
}
