Is Jdk a compiler?

The JDK includes "javac" tool which compiles Java source code to a format (byte code) that's very optimized, but not quite machine language, which your hardware can understand. Therefore, JDK also comes the "java" tool, which parses the byte code and converts it to machine language, executing it right away.

How does Compilation work in Java?

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then executes at runtime. Java source code is compiled into bytecode when we use the javac compiler. When the bytecode is run, it needs to be converted to machine code.
