I'm at the beginning/middle of a project that we chose to implement using GWT. Has anyone encountered any major pitfalls in using GWT (and GWT-EXT) that were unable to be overcome? How about from a performance perspective?

Ok, I may resort to a tad ranting here, so let me apologize in advance, but I'm really curious if others find this pattern annoying too (and I wonder if it is a justifiable pattern)…

why is the Double.parseDouble making 9999999999999999 to 10000000000000000 ? For Example :

We are running a Java application that sometimes "freezes" because some thread is using almost all the heap. Despite the JVM doing Full GC that last more than 60 seconds the application never dies with OutOfMemoryError.

I'm playing with some piece of code calculating the time needed to compute some Java code to get a feeling of the efficiency or inefficiency of some of Java's functionality. Doing so I'm stuck now with some really strange effect I just can't explain myself. Maybe someone of you can help me understand it.

At school we are currently learning sorting algorithms in Java and I got for my homework the Heap Sort. I did my reading, I tried to find out as much as I could, but it seems I just can't grasp the concept.

I am shopping for a STATIC ANALYSIS TOOL that can tell me if our code suffers from deadlocks, race conditions and bad practices in general.

I have written a bubble sort algorithm to sort a linked list. I am a Java beginner and trying to learn data structures. I am confused why my second element is not sorted properly.

I'm a naughty programmer, and until now I haven't handled errors properly (e.g. just catching a java.lang.Exception, printing a debug message, and moving on). When I do "handle" them, it's simply been to shut the compiler up.

I am from Turkmenistan and I used JDatePicker to get a date. Is it possible to use the Turkmen locale in Java?

Why can't we make arrays in Java like this: int marks[5];

I've been doing a lot of reading about how using singleton classes is becoming bad practice in programming due to hidden dependencies, hard to test etc etc.

I have an enum public enum Days { SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY

I'm looking for a library to do numerical computing in Scala (or Java, although something that can use scala functions would be way nicer!) with at least the following capabilities:

Comparison of HashMap and Hashtable source code in jdk 1.6, I saw below codes inside HashMap

I watched the Oracle OTN Virtual Event: Java SE and JavaFX 2.0 (28 Feb 2012) and while talking about the new diamond operator (that Map<String, List<String>> myMap = new HashMap<>(); thing) the speaker mentioned that it was not as simpleto implement than one might think, as it is not a simple token replacement.

This question is a corollary to: Editing programs “while they are running”? Why?

I have a Java program that runs on my Ubuntu 10.04 machine and, without any user interaction, repeatedly queries a MySQL database and then constructs img- and txt-files according to the data read from the DB. It makes tens of thousands of queries and creates tens of thousands of files.
