Hi Debajit,
If you are a beginner in the programming field and you are willing to learn a language, then C++ would the best because it is more beginner friendly. You can learn Java and Python also but that would be a bit harder for you.
Now, coming to placements, Java and C++ are most commonly asked by companies in the placements. So, you have a choice between C++ and Java. From two of these C++ takes an edge in the competitive coding while Java also has development capabilities,
So, decide yourself which one would be better suited.
Feel free to ask doubts in the Comment Section.
I hope this information helps you.
Good Luck!
