It's completely free and you just need a Udemy account to join this online course.Īnother differnce over JDK vs JRE is that when you install JDK in your machine, JRE comes automatically and you can check this by going to your JAVA_HOME or Java installation directory.

Java Virtual Machine can be customized like we can specify starting memory or maximum memory of heap size located inside JVM at the time of JVM creation. Java Virtual machine is at the heart of Java programming language and provides several features to Java programmers including Memory Management and Garbage Collection, Security, and other system-level services. JVM is responsible for converting byte code into machine-specific code and that's why you have different JVM for Windows, Linux, or Solaris but one JAR can run on all this operating system. Java Virtual Machine is get created when you run a java program using java commands like java HelloWorld.
