The Enhanced for loop in Java 1.5 (5.0)

There have been a lot of enhancements to existing features in Java 1.5 (5.0). One of the simplest improvements is to the most commonly used for loop.

Here's how it worked prior to version 1.5:


vec is a Vector

SomeObject obj;

for(int i=0;i<vec.size();i++)
{
    obj = (SomeObject) aVec.elementAt(i);
    //code to use obj
}
Now, here's how it works in version 1.5:


for (Object aVec : vec)
{
    obj = (SomeObject) aVec;
    //code to use obj
}
As you can see, the loop incrementor is now handled implicitly.
