jdk1.5 is sun's tiger project

collection framework is better with generic introduction

now we can add only related objects in collection

e.g

ArrayList<String> al new ArrayList<String>

ArrayList<Integer> al new ArrayList<Integer>
3
StringBuilder class for usync StringBuffer

The base of JDK1.4 is reused with the JDK1.5 and the addtions are generics autoboxing and annotations etc.. till now the 1.4 is in use because 1.4 is extensively tested by vendors and it is the stable version of JDK by SUN.
