In this tutorial you will learn about the Java Development Kit (JDK) and its application with practical example.
Java Development Kit (JDK)
Java Development Kit (JDK) is a software development kit that contains tools needed to develop Java applications, and JRE to run the program. We can think of JDK as a set of JRE and Development Tools. When we download JDK, JRE is also downloaded, and we don’t need to download it separately.
In addition to JRE, JDK also contains a number of development tools such as Java Archive (jar), Java Compiler (javac), Java Disassembler (Javap), Java Debugger (jdb), Java HeaderFile Generator (javah), Documentation (Javadoc) and many others.
