Your question is not clear;

I think you are looking for something like "set"

// Create the set
Set set = new HashSet();
// Add elements to the set
set.add("a");
set.add("b");
set.add("c"); 

...

// Determining if an element is in the set
boolean b = set.contains("a"); // true
b = set.contains("d"); // false

Can you define what a cluster is?
Do the points enclose a shape such that a line connecting the outer most points forms a boundary for a region?

Sorry, I thought you wanted help designing and writing this program.
If you want help, could you define "k-means or hierarchical clustering of points"?
Can you define what a cluster is?
