How do you exit sub in Java

In vb you can say

Code:

---

if filename = "" then exit sub

---

and that will stop the function from executing more code, how can I do the same in java?

Here is what I got so far but its not compiling

Code:

---

    private void jToggleButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                             

 
       
        String filename=jTextArea1.getText();
       
        if filename = "" then return;
       
       
    }

---

What do i have to put instead of 'return'?

The return keyword will do exactly the same as Exit Sub in VB

And by the way:

vb Code:

if filename = "" then return;

Oh my god
It's:

Code:

---

if( filename.equals("") ) return;

---

lol, I accidentally put 'then' , java doesn't use then. Its gonna be hard getting used to Java again. Thanx brotha

Never mind. Correct it right now. It is good to see pal.
