Knowledge is Power Supreme.......

Does the title speak to itself, well it was intended to, but if its not, read through so that it makes sense.

Thought, Let me also put my contribution :-) I was working with the earlier versions of java [1.42] until i joined my new company in July 07. I realized the power of tiger only when i literally starting doing development using Java 5.0 The main concepts i would like to share are 1. Java Generics 2. Advanced features of Collections The items in the list are of utmost concern to us, the developers. Java 5.0 has made developers life lot more easier. Java Generics By introducing the java generics, the developers now are not required to do the class typecasting at each and every point. An example would me more apt. Here is a typical usage of that sort: List myIntList = new LinkedList(); // 1 myIntList.add(new Integer(0)); // 2 Integer x = (Integer) myIntList.iterator().next(...

We have to query both the tables, get the records and show them in same line if they both have same data for Col1 in their tables. OK, in normal world, i would have been thinking of putting two outer joins and then integrating the results in the Java using some crap logic. This is due to the fact that an outer join extends the result of an inner join by including rows from on...
