Program Explanation

1. Create a frame with background color & specific size. frame.setBackground(Color.white); is used to create the frame background color as white. frame.setSize(500,500); is used to set the width and height of the frame.
2. frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); is a default close operation for the frame.
3. Create a label with a setBounds() values and add it to the frame by using frame.add();.
JLabel label=new JLabel(); –> Used to create the label.
label.setBounds(0,100,500,50); –> Sets the position of label.
frame.add(label); –> It will add the label to the frame.
