In java swing or GUI, commonly when we want to read some text or string form textfield we have use to use button..example:

String Text;
JTextField Field;
//when button clicked
if(e.getSource==Button)
{
Text = Field.getText();
}

Instead of using this method, how to read the string from textfield when users press enter?

You need to attach a component listener to the widget and then use getText to retrieve the information when the enter key activates the callback.

Q...

Thanx..its working...
