# Executing an expression

Executing an expression evaluates an expression but does not display a result.

If you select the expression to execute and click the Execute button in the toolbar, no result is displayed, but the code is executed.

For example, if you type and highlight `System.out.println("Hello World")`, and click the Execute button, Hello World appears in the Console view, but no result is displayed in the scrapbook editor or the Expressions view.
