| Editor Templates |
| </h1> |
| <p> |
| 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 (<strong>Ctrl+Space</strong>). |
| </p> |
| <p> |
| 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 |
| <code>for</code> will present you with a list of possible templates for a for loop. You can |
| choose the appropriate template by name (<code>iterate over array</code>). Selecting this |
| template will insert the code into the editor and position your cursor so that you can edit |
| the details. |
| </p> |
| |
| <p> |
| Templates can contain <a href="../concepts/concept-template-variables.htm">template |
| variables</a>. Variables mark the editable locations. They can be resolved to a concrete |
| value when the template is evaluated in its context. They can also provide a list of |
| alternative proposals valid at the given location. |
| </p> |
| <p> |
| Many common templates are already defined. These can be viewed with the <a class= |

| existing ones. |
