System.out.println();
System is the Class in which out is static object of
class PrintStream which refers t othe standard output ie
console output,
and PrintStream class contains the method println()
which will be accessed using PrintStream object out.
Since out is static so it can be only accessed using
class name in which it contains.
so System.out.println(); simply invokes println()
method to output specified data to standard output console.

Draw a UML class diagram for the code fragment given below: public class StringApplet extends Applet { private Label sampleString; private Button showTheString; private ButtonHandler bHandler; private FlowLayout layout; public StringApplet() { sampleString = new Label(" "); showTheString = new Button (" Show the String"); bHandler = new ButtonHandler(); layout = new FlowLayout(); showTheString.addActionListener(bHandler); setLayout(layout); add(sampleString); add(showTheString); } class ButtonHandler implements ActionListener { public void actionPerformed(ActionEvent e) { samplestring.setText("Good Morning"); } } } Note: The methods need not be indicated on the diagram.
