thank you soooo much for the reply...am looking for more than that..
am doing a project,to make it simple i gave the program of addition.
sir/mam, i developed frontend with netbeans with buttons and textarea..
am executing a clustering algorithm by pressing the button.
the custering algorithm reads the data from database and it performs clustering.everything is going well.
but the output is not displayed in the textarea...as the textarea is created in input.java file
ouput is executed and it has print stmt in the cluster.java file....where i cannot return values...but i want this cluster.java file to recognise the textarea created in the input.java file..pls how to do this..
