JDK : JDK contails JRE and JVM both. JDK is required to
complie. JDK contains of many .exe supporting files and
javac, javap, java,javaw, javaws ,all these are helping to
compile the java programs. If we have to compile our own
written java program JDK should be define in our classpath.
after compilation it converts the code into the bytecode.

JRE : JRE is needed for run time environment. It contains JVM.

JVM : Java Virtual Machine converts the bytecode into user
understandable code. without JVM we cannot run our Java
codes on any system. JVM converts the bytecode got after
compilation into machine level code by understanding the
hardware and operating system combination.

Is there any way to find whether software installed in the system is registered by just providing the .exe file? I have tried the following code but its just displaying the directory structure in the registry. Here the code : package com.msi.intaller; import java.util.Iterator; import ca.beq.util.win32.registry.RegistryKey; import ca.beq.util.win32.registry.RootKey; public class RegistryFinder { public static void main(String... args) throws Exception { RegistryKey.initialize(RegistryFinder.class.getResource("jRe gistryKey.dll").getFile()); RegistryKey key = new RegistryKey(RootKey.HKLM, "Software\\ODBC"); for (Iterator subkeys = key.subkeys(); subkeys.hasNext();) { RegistryKey subkey = subkeys.next(); System.out.println(subkey.getName()); // You need to check here if there's anything which matches "Mozilla FireFox". } } }
