method / if statement

[SomethinCool]

can someone explain to me why this isnt working? It is supposed to show the next form if the username is correct and it doesnt work. What am I doing wrong here?

 private void btnLoginMouseClicked(java.awt.event.MouseEvent evt) {                                      

        if(txtUsername.getText() == "jeff"){
            //If login is successful, load main frame
            MainFrame newMainFrame = new MainFrame();

            newMainFrame.setVisible(true);

            this.dispose();
        }        
       
 }

I did a System.out.println(txtUsername.getText()); before the if statement and it did show up. I don't understand why the code in the if statement is not being executed. Thanks.

txtUsername.getText()

Put a system.out.println statement outside the if statement with that line of code. also make sure you trim the text to get rid of white space. another thing, you should use .equals() in string comparison rather than ==.

if ( txtUsername.getText().trim().equals("Jeff") )
{
}
