tf1 = new TextField(15);
tf2 = new TextField("I Display", 15);

We know a constructor gives properties to an object at the time of object creation itself and is the case with TextField also. The tf1 creates a text field with 15 characters width but user can enter any number of characters and the extra characters entered can be seen using arrow keys. The second text field object tf2 by default displays a text "I Display" in the text field which user can change.

Explanation of Java TextField Methods

tf3 = new TextField( );
tf3.setText("Your way 2 java");
tf3.setFont(new Font("Monospaced", Font.BOLD, 15));

The text field tf3 object is created without any properties, and later, properties are set explicitly with setXXX() methods. setColumns() method sets the width of the text field and setText() method places the text. Background and foreground colors are set with setBackground() and setForeground() methods. Similarly, font is set with setFont() method.
