Structures and objects don’t even exist in the resulting code – they’re merely an abstraction that gets translated to hard-coded offsets into memory buffers. What is the Java Programming Environment? JRE contains the JVM, the java classes/packages and the run-time libraries. Reply ↓ Mr.Khun Nyan Thein Jul 20, 2016 at 4:06 am Good thank you so much!!!

Java Development Kit (JDK) The JDK is a superset of the JRE, and contains everything that is in the JRE, plus tools such as the compilers and debuggers necessary for developing The JDK includes the JRE plus command-line development tools such as compilers and debuggers that are necessary or useful for developing applets and applications. But truth is even if you don't import any library there are some libraries which will be imported implicitly. Consequently, you only require Java Access Bridge 2.0.2 for Java SE 6 and earlier.

The JVM doesn't understand Java typo, that's why you compile your *.java files to obtain *.class files that contain the bytecodes understandable by the JVM. In other words if you are a Java programmer you will need JDK in your system and this package will include JRE and JVM as well but if you are normal the Java library code.
