It would depend on alot of factors, time spent in preparation, analytical and logical skills, prior java knowledge, listening skills and most important patience and presence of mind.

Here are some tips though to crack your Java Interview

- Focus mainly on Data Structures and Algorithms, additionally work on your problem-solving skills

- Understand the requirement of the Job role, mostly they wouldn't ask outside of it.

If you're looking for some resources, few of my fav sites are Hackerearth, InterviewBit, GFG

Although I would strongly recommend solving questions from Interviewbit
gamifies the experience of practicing for your interview and includes lots of sample problems, company based interview questions, topic wise Interview Questions. The problems have been categorized into topics and then micro-concepts within topics. Each problem has hints and editorials with them.

You can practice problems from here: https://www.interviewbit.com/java-interview-questions/
