I am using Netbeans and I have tried installing SPMF in Netbeans. Now when I run any algorithm, I am getting 'Null Pointer Exception' error. Please suggest how to remove this error?

Hello,

Null pointer exception is quite general, and which algorithm are you running with which file? Can you give the details and also the full error?

One of the possible reason is that the files have not been installed properly into NetBeans. Another possibility is that you have tried to load some input file but you did not place the file in the correct directory. Thus the software cannot find your input file and give a null pointer exception.
