There are two ways to transfer data. These are:
1. The diagram below displays the Drag and drop (DnD) functionality of Swing.
2. The diagram below displays the cut/copy and paste functionality of Swing. That is the clipboard transfer via cut/copy and paste. The path of the data is shown by the arrows.
To be more precise, first of all the bundling of data takes place into a package known as Transferable to begin Data Transfer. Then the data gets extracted by an object i.e. TransferHandler from the Transferable which is provided by the component.
