Why Companies are still using Java when we have Python?

1.) SPEED AND TIME CONSUMPTION

Firstly, Java uses Compiler and Python uses Interpreter. A Compiler converts your code to machine-readable code block by block. An Interpreter does the same by doing it line by line which takes more time naturally.

2.) EXECUTION TIME

Execution of Java programs by JVM(Java Virtual Machine) is much faster than Python

3.) LANGUAGE TYPE

Java is statically typed language whereas Python is dynamically typed language.

4.) DISTRIBUTION

Generally speaking, distribution of Java software is easier compared to Python software.

Above points are just brief advantages Java has over Python. Having said that, every language has its own advantages and disadvantages.
