A JButton on Java is a button used for G.U.I (graphical user interface) and displays a button on a window created which can be programmed for different tasks.
On the lower level of Java, a "reference" can be thought of like a pointer in C. It is essentially an integer which refers to (points to) a location in memory where the object data exists. // "button" is a reference to a JButton with a "1" on it (the object). JButton button = new JButton("1");
There is no sizeOf() operator in Java.

We can create a exception sub class by extending Exception class available in java

If you are using the Button class, you can't. java.awt.Button only allows for text to be displayed. However, if you are using the javax.swing.JButton class you can make a call to JButton.setIcon(Icon) to add an image onto your button. Example: // Let's create a new button JButton button = new JButton(); // Load the image in img.gif (this image may be a GIF, JPG, or PNG) ImageIcon icon = new ImageIcon("img.gif"); // Add the image to the button button.setIcon(icon);
java is an object oriented programme it is similar to c++ so if you know very well in c++ you can easily figure it out.
You don't have to rewrite your code to get it working 2 or more OS' That cuts down development cost and time by a lot.
There are three different methods /functions in java are there : 1)computational methods.2)manipulative methods.3)procedural methods.
Java is a platform independent language becoz of the bytecode magic of java. In java, when we execute the source code...it generates the .class file comprising the bytecodes. Bytecodes are easily interpreted by JVM which is available with every type of OS we install.
