Templates

Templates are a structured description of coding patterns that reoccur in source code. The Java editor supports the use of templates to fill in commonly used source patterns. Templates are inserted using content assist (Ctrl+Space).

For example, a common coding pattern is to iterate over the elements of an array using a for loop that indexes into the array. By using a template for this pattern, you can avoid typing in the complete code for the loop. Invoking content assist after typing the word for will present you with a list of possible templates for a for loop. You can choose the appropriate template by name (iterate over array). Selecting this template will insert the code into the editor and position your cursor so that you can edit the details.

Many common templates are already defined. These can be browsed in Window > Preferences > Java > Editor > Templates. You can also create your own templates or edit the existing ones.
