Hi @BalarajeshReddy, welcome to the Instructor Community! This is a space for instructors to help each other and connect. If you're a student and have any specific questions about a course you're taking on Java, I recommend navigating to the course lectures and posting your question in the Q&A section. The instructor and your fellow colleagues will be more equipped to answer your questions.
All the best
