difference between jdk1.4 and jdk1.5

hi

i had registered recently.

i need to konw main diffrence between jad1.4 and jdk1.5

what new features added newly in jdk1.5

I encountered once that 1.5 support setBlob or something similar, and you can get a Blob object from ResultSet in 1.5, but you can not do it in 1.4

main difference is introduction of generic class in jdk1.5.

[B]New Feature[/B]:Annatations(it eleminates XML coading in J2EE Application Development);

[B]New Feature[/B]:Generic's For Different Type of declerations in any level;
