Integrate Rapidminer wtih java application

The easiest way is to create a process in Rapidminer and use this created process in your java appilcation.
You can run this process by simply creating a instance of Process class and pass the instance of class File containing name of file as argument to the constructor of Process.


Below is the java code to run process from rapidminer to perform the clustering (K-means).

Input:-----     Excel file containing dataset(numerical).

Output----- Clustered Output labelled with cluster_0, cluster_1, cluster_2.............
