• Basic Java Multi-Threading Question

  - by Veered

  When an object is instantiated in Java, is it bound to the thread that instantiated in? Because when I anonymously implement an interface in one thread, and pass it to another thread to be run, all of its methods are run in the original thread. If they are bound to their creation thread, is there anyway to create an object that will run in whatever thread calls it?

• Create Word/RTF file with table of contents from Java

  - by Glen

  Hi, I want to create a Word or RTF file with a table of contents (with links to each section) from Java. From my understanding, iText & Apache POI do not support generating a table of contents. Some clients of the app still use older versions of Word, so I need a library that supports the older Word doc format. Does anyone know how I can do this? Thanks, Glen

• How to sanity check a date in java

  - by Bloodboiler

  I find it curious that the most obvious way to create Date objects in Java has been deprecated and appears to have been "substituted" with not so obvious to use lenient calendar. So... How do you check that a date given as a combination of day, month and year is a valid date? For instance a date 2008-02-31 (as in yyyy-mm-dd) would be invalid date.

• Java Deflater strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY

  - by Keyur

  I'm trying to find a balance between performance and degree of compression when gzipping a Java webapp response. In looking at the Deflater class, I can set a level and a strategy. The levels are self explanatory - BEST_SPEED to BEST_COMPRESSION. I'm not sure regarding the strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY I can make some sense from the Javadoc but I was wondering if someone had used a specific strategy in their apps and if you saw any difference in terms of performance / degree of compression. Thanks, Keyur
