Java Help Urgent Programming help Need Now

Write   a   method   that   takes   an   array   of   Object   as   parameter,   and   
reverse   the   array.   
Hints:   
• Declare   the   method   as   static   since   we   want   to   test   this   method   by   
main   method. Method   main   is   static   and   can   only   call   static   methods   
directly.
• We   do   not   need   to   return   anything,   the   change   applies   to   the   array   
parameter.
• A   possible   way   to   reverse   an   array   is   to   use   two   ends,   one starts   from   
the   leftmost   index   the   other   starts   from   the   rightmost   index, then   we   
swap   these   two   elements, afterwards,   move   the   leftmost   index   one   
step   to   the   right, and   move   the   rightmost   index   one   step   to   the   left,
continue   the   above   procedure   until   both   ends   meet.

I actually posted it on programming forums, but my godfather also told me to put it up here as well.

thank you

Then it is inappropriate for you to be asking other people to do your assignment for you. When was this assignment given, and for what level of education is it for?

Why are you turning to a gaming and product forum for coding help? Lol

He answered that above, actually. I guess I may have been a bit harsh. I admit that I am biased since I was a virtual school teacher for a little while, but it always irked me when students would cut and paste answers from message boards and "tutoring" sites (not that Humza was going to do that). I guess it still hits a nerve. Sorry about that.  :-\

Oops, only read the first message.

I'll do my best to answer without just giving a cut and paste answer. Hopefully it isn't too late for you if you haven't finished it. As others have said, this isn't the best place to post questions to programming assignments. Don't worry about it now, but in the future it will probably be better to just post it on a different forum that is dedicated to computer programming.

A static method is one that simply one that is constant between all instances of an object, and thus cannot use any variables that are local to that object. To make a method static, you just have to put the word "static" before the return type of the method.

As what you posted says, you can make a loop that goes up to half way through your array. At every iteration you have to swap the ith element with the (i - 1)th element.

I'll leave the details up to you. Hope that helps you, again, if it's not too late.
