If you're running this within netbeans, this error can't/shouldn't occur (then you did quite a number on how you managed to misconfigure this project!). If you're running it from the command line:

cd ..
java pragnya.Pragnya

Alternatively, assuming JDK11+, you can just run java Pragnya.java (not javac, then java - just java the source file).

Read up on packages and classpath structure if you want to know why you need to it this way.
