Hi, would appreciate if anyone can help me out on this.
I have a series of keys and values that I would like to add into a hashmap.
I am printing out the order using the values, only one key will be selected although I have got 3 keys. I am sure that this is the problem of the same values in my Arraylist. Can anyone suggest a solution for this?
What i need is that if it had taken out the 1st key then it will move on to retrieve the 2nd key and so on even though the values are the same.
You'll find its API documentation here. And you'll find the API documentation for the java.util package, which contains all of the collections, here. Finally, you will find the Collections tutorial here.
Those should provide a much better learning tool than me trying to explain some specific code. Good luck!

I had spent some time reading through the API and tutorials but am unable to find a sample for comparing objects in Map.Entity.
Is it possible for you to provide me with some codes relating to comparing Map.Entity objects to work on with.

I revisit the codes and tried some sample codes and found out certain things I would like to clarify with you.
Why do we need to create a Set Map.Entry object to store the rank. entry set?
I tried it by just storing it in the arrayList and it still works...Any reason why you particularly store it in a Set?
That line of code is identical to the first two lines of code that I posted. The only difference is that my code assigns the entry set to a variable and then passes that variable to the ArrayList constructor, and yours passes the entry set directly to the ArrayList constructor. The end result is the same in both cases.
I did it that way because many people find it harder to understand complicated one-liners. Especially beginners.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
