I have installed JRE 1.7 in my system and no JDK and when I wrote a program in eclipse, eclipse is still able to compile it and run it. As per my knowledge, compiler is available in JDK and interpreter is available in JRE. Interpreter will take .class files. But what about .java files?

Is it because of JIT compiler which is available in JVM?

    Eclipse has its own Java compiler – apangin Feb 02 '18 at 07:32

    Even though Eclipse can compile with only a JRE it is still better to use a JDK because then Eclipse will have access to the runtime library JavaDoc and source code. – greg-449 Feb 02 '18 at 07:48
