Eclipse tip: Scrapbook

20 Jan

Quite a few times I find the need to try out small snippets of code, like string manipulation. Creating a new class for this is a pain. Fortunately Eclipse provides an easy way to do this. All you have to do is create a scrapbook (File > New > Scrapbook Page) and try out your code here.


The scrapbook has syntax highlighting and code completion. This lets you execute snippets and see the results or even inspect the results. This is a big time saver.

    Is there an easier way than highlighting the code you want to execute?

    AFAIK the only way is to highlight the code you want to execute. I assume its this was as you can have a lot of different snippets in your scrapbook.

    i just tried the scrapbook feature in eclipse 2.1.2, and have big problems with it. searching for help i found your page, maybe you have an idea what’s wrong:

    - imported packages: java.text.* and java.util.*;

    - your "string".replace() example was ok.

    - this hangs in FileInputStream.open() (!?):
    Calendar.getInstance().toString()

    - this hangs in FileInputStream.open() (!?):
    new SimpleDateFormat("dd.MM.yyyy").format(new Date());

    thanks in advance for any help,
    victor
