The Color class is a part of Java Abstract Window Toolkit(AWT) package. The Color class creates color by using the given RGBA values where RGBA stands for RED, GREEN, BLUE, ALPHA or using HSB value where HSB stands for HUE, SATURATION, BRIcomponents. The value for individual components RGBA ranges from 0 to 255 or 0.0 to 0.1.

AWT hierarchyContainerThe Container is one of the components in AWT that contains other components like buttons, text fields, labels, etc. The classes that extend Container class are known as containers such as Frame, Dialog, and Panel as shown in the hierarchy. Types of containers:As demonstrated above, container refers to the location where components can be added like text field, button, checkbox, etc.
There are in total, four types of containers available in AW, that is, Window, Frame, Dialog, and Panel. As shown in the hierarchy above, Frame and Dialog are subclasses of Window class. WindowThe window is a container which does not have borders and menu bars. In order to create a window, you can use frame, dialog.

Java Swing TutorialJava Swing tutorial is a part of Java Foundation Classes (JFC) that is used to create window-based applications. It is built on the top of AWT (Abstract Windowing Toolkit) API and entirely written in java.Unlike AWT, Java Swing provides platform-independent and lightweight components.The javax.swing package provides classes for java swing API such as JButton, JTextField, JTextArea, JRadioButton, JCheckbox, JMenu, JColorChooser etc. Difference between AWT and SwingThere are many differences between java awt and swing that are given below.

How to create puzzle game and pic puzzle game in swing?. How to create tic tac toe game in swing?Hierarchy of Java Swing classesThe hierarchy of java swing API is given below. Commonly used Methods of Component classThe methods of Component class are widely used in java swing that are given below.
MethodDescriptionpublic void add(Component c)add a component on another component.public void setSize(int width,int height)sets size of the component.public void setLayout(LayoutManager m)sets the layout manager for the component.public void setVisible(boolean b)sets the visibility of the component. It is by default false.Java Swing ExamplesThere are two ways to create a frame:. By creating the object of Frame class (association). By extending Frame class (inheritance)We can write the code of swing inside the main, constructor or any other method. Simple Java Swing ExampleLet's see a simple swing example where we are creating one button and adding it on the JFrame object inside the main method.File: FirstSwingExample.java.
