Thread: Java application

I am last year computer science Student. I am learning java programming language. In our last lecture our sir asked one question like How to terminate a Java application? Not any of us able to give answer of it. Can anybody tell me how to terminate a Java application? Please help me.
Thank you.

It is very easy program. In the following program I have form one class called as Sample File. In this class I have build one variable called as "static BufferedReader BR1". After this I use BR1 in getContent() method.

public void windowClosing(WindowEvent es)
{
try
{
int options = JOptionPanse.showConfirmDialogs(null, "are you sure want to close the application?",
"Select correct Options", JOptionPane.YES_NO_OPTION);

SampleFile.BR1.close();

if(options == 0)
System.out.println("Hi");
}
catch(IOException ies)
{
JOptionPane.showMessageDialog(null,"one error shows here ");
}
}
