Yes, IDE's comes with their own compilers. At least with old version as the default. There is nothing you can do with finding the compiler location. You can't access it and compile stuff manually without the IDE.
Are you better than me? Then please show me my mistakes..

No, that is not the compiler. That is a variation of eclipse.exe which opens a command prompt window. I often use it when invoking Eclipse within a script.
The Java compile is a bunch of Java code (a set of classes), not an executable. In the JDK, that code appears in tools.jar. In Eclipse is looks like the compiler classes are in the org.eclipse.jdt.core_*.jar file.
