The "Java Development" menu in Eclipse

The "Java Development" menu in Eclipse contains three commands used to update either the code or the model according to modifications made.

The “Java Development” menu commands are used as follows:

· “Show in model” selects the currently edited class in the model.

· “Update model” updates the model according to the modifications made in the Java source code of the active editor.

· “Update from model” updates the source code from the modifications made to the model.

Warning: The supposition is made that when the model is updated, you have already validated these modifications in Eclipse, by saving code modifications (CTRL-S). If this is not the case, Eclipse will ask you before updating the model.
