Between all three mentioned, I'll advice to go for Java. Among these java captures major market share. Due to its open source attribute most companies invest in Java for their application development. Also java has some unique features which keeps it at upper hand over other two. But yes going towards learning curve, Java requires more time to get proficiency. But in end you will enjoy upper hand after learning Java.
Best of Luck.!!

To get tutorials for Java you can visit tutorialspoint.com . Its good site to start with. But strongly recommend to join some code practice platform like techgig.com or hackerank. They will provide sample problems to solve along with learning.
Lastly, don't forget to refer java docs from oracle's official website for the specific version of java you are learning.
HAPPY LEARNING. KEEP PRACTICING.

Every technology has great oppurtunity if you have sufficient knowledge about it. After CCNA and having good knowledge you have chance to work in companies like CISCO.

.net also has high usage as many websites and softwares uses .net.
So every technology has oppurtunity, you just need to go wid your interest and with full dedication
