Answer 1

Why? Because it's not doable to directly program in binary
How does they work? They get converted to binary

Answer 2

With a compiler, it follows an algorithm which knows how each lines of codes could be directly rewritten in binary

Answer 3

basically the high level programming languages compiling the code line by line to multiple programming languages, that's why they called high level programming languages.

Java -> C / C++ ( I guess ) -> assembly -> binary.

Answer 4

and how computer convert the codes?
