Question about syntax

Question

hi,
If I have a class like this...
public class Sample implements ActionListener{
       Socket s;
      Button test = new Button("TEST");
    Button boo = new Button("boo");
    PrintWriter out = new PrintWriter();
    public Sample(){
    test.addActionListener(this);
     public void actionPerformed(ActionEvent e ){
     if(e.getSource()==test)
      s = new Socket("local host", 8888);
     else if(e.getSource()==boo)
            out.println("testing..");
when someone presses the test button, (which would create the socket,) and then presses the boo button, is the socket still available or do I have to instatntiate  it again?
Thanks alot

Answer 1

public class Sample implements ActionListener
Socket s;
Button test = new Button("TEST");
Button boo = new Button("boo");
PrintWriter out = new PrintWriter();
public Sample()
test.addActionListener(this);
public void actionPerformed(ActionEvent e )
if (e.getSource()==test)
s = new Socket("local host", 8888);
else if(e.getSource()==boo)
out.println("testing..");
When someone presses the test button, (which would create the socket,) and then
presses the boo button, is the socket still available or do I have to instatntiate it again?
Thanks
If the user presses the test button first, an object of type Socket is instantiated,
which is local to the actionPerformed() method. It will be accessable within that
method. However, If the user clicks on the boo button first, it will not be accessable
because it hasn't been instantiated yet.
