How can I get the content before the text changes to a textbox?

You can declare a string as the content of the previous Temporary change. In the textchanged event process, assign the current value to this temporary variable. In the next textchanged event, this temporary variable is the content before the change. Can this happen?

Simplified. It is no different from getText...
Public String getString (JTextFiled t ){
Return t. getText ();
}
You can do it yourself... it's totally unnecessary...
