Here's a Tl;Dr for everyone:
Java is normally first compiled to an intermediary language which is stored in a JAR File. This file is then run by the Java Virtual Machine. Initially the JVM interprets the bytecode but as time passes it slowly compiles the code to native machine language. So Java is in essence, both Interpreted and Compiled. (As a side effect of this Java is the only language that gets increasingly faster as time passes; While most other programs written in other languages will stay at the same speed throughout, Java programs tend to execute somewhat slowly when first starting up, but will speed up over time and can get as fast as even C/C++ programs are)

I will mention that the official Java compiler has the option to compile Java directly to the target executable instead of JVM bytecode however

Thanks sir you answered on my all questions ❤️

[DrYawningMoon]

I have a question that why we use both the compiler and interpreter in java to execute final programs. Why not only interpreter or a combination of compiler and executor?And which one would be better(faster/efficient)?
