# Presentation options for Java views

## Showing and Hiding Method Return Types

Several Java views (e.g. Outline, Members) present methods and can also show their return types.

To show method return types in Java views select or clear the Show method return types checkbox in the Java > Appearance preference page.

## Showing Full or Compressed Package Names

The Package Explorer and Packages views can show full or compressed package names.

To show full package names:

- Clear the Compress all package name segments, except the final segment checkbox on the Java > Appearance preference page.

To show compressed package names:

- Select the Compress all package name segments, except the final segment checkbox on the Java > Appearance preference page.

  Compression patterns control how many characters of each package name segment are displayed. The last segment of a package name is always displayed.

  A compression pattern of "." indicates that only the separating periods are shown to represent a segment. A digit (n) in a compression pattern represents the first n characters of a package name segment. Examples are the best way to understand compression patterns. The package org.eclipse.jdt would be displayed as follows using the example compression patterns:

  . ..jdt

  0 jdt

  2~ or~.ec~.jdt

  3~ org.ecl~.jdt
