The Java development toolkit (JDT) contributes a scrapbook facility that can be used to experiment and evaluate Java
code snippets before building a complete Java program. Snippets are edited and evaluated in the Scrapbook page
editor, with resultant problems reported in the editor.
From a Java scrapbook editor, you can select a code snippet, evaluate it, and display the result as a string.
You can also show the object that results from evaluating a code snippet in the debuggers'
Expressions View.
