Difference Between SDK and JDK (With Table)

SDK stands for the software development kit and is described as a set of software tools used worldwide to create an application or a program. There are various platforms to develop an application, and every forum has its SDK. For example, for ios application development, the developers use ios SDK. The SDK tools include processes, API, libraries, compiler, debugger, code samples, guides etc. 

JDK stands for the Java development kit. JDK can be defined as a software development kit for writing a program in java. It is one of the three core technology packages used by java, i.e. JVM, JRE and JDK. JDK consist of a set of development tools that help develop java-based software. It has various versions, but the most commonly used version is Java 8.

Comparison Table Between SDK and JDK

What is SDK ?

SDK stands for the software development kit. It is a set of software or development tools used by the various developers to create an application or a program on any platform of their choice. The SDK tools include libraries, compiler, debugger, processes, API, code samples, guides etc. SDK are of various types; it has a different kind for the other platform. For example, for android application development, one might need an android software development kit, etc.

A good software development kit should be easy to use by the developers, contain thorough explanations of codes, not negatively impact CPU or battery, etc. SDK consists of API or application programming interfaces that help connect new applications or projects at a source text level. The libraries present in SDK contains the sample codes, which further allows the programmers to write to new codes or programs.

SDK also consist of documentation. These documentations tell the developers how to use API; they provide them with tutorials as well. There are some SDK that might contain some rules and agreements. In order to use such SDK, a developer has to acknowledge those rules first. SDK can be said to be the source of any and every program and application made by various developers. The games we play, apps we use for communication and sharing data are made possible because of SDK.

What is JDK?

JDK stands for the Java development kit. Java is an object-oriented, environment-friendly programming language. It usually uses three core technology packages, i.e. JVM or java virtual machine, JRE or java runtime environment and JDK or java development kit. JDK can also be defined as a software development kit for java. It allows the developers to create a java program that can execute on JVM and run by JRE.

There is often a confusion between JRE and JDK. JRE is a set of development tools that help run a java code, whereas JDK is a set of development tools that help develop java-based software. When a person downloads the java development kit, the first step is to choose the version. Most commonly used version is Java 8, but it depends on different people and the type of work they are using it for.

After selecting the version, the next step is to choose the java package. These packages include Java enterprise edition or JEE, Java standard edition or JSE and Java mobile edition or JME. Developers select these packages according to the needs of their projects.

 JDK is generally downloaded along with with the NetBeans IDE or integrated development environment. IDE manages the compilation of code. However, JDK contains an interpreter, compiler, etc. already, but using IDE provides a better environment to work.

Main Differences Between SDK and JDK

1. SDK stands for software development kit whereas JDK stands for Java development kit.
2. SDK is a set of software or development tools used to create an application or a program on any platform. In contrast, JDK is a set of development tools that allows a programmer to write a program using java language.
3. SDK have various types such as android SDK, ios SDK, java SDK, etc., on the other hand, JDK does not have any classes. However, it does have various versions.
4. SDK includes libraries, sample code, supporting documentation etc., whereas the JDK consists of the programming tool’s selection components.
5. JDK is a subset of SDK which makes it interdependent. 

Conclusion

SDK is a set of development or software tools used by developers to create an application or a program on any platform. SDK is of multiple types. Every platform has its own SDK. Simultaneously, JDK stands for the Java development kit and is described as a software development environment used to develop java applications.

Java language usually uses JVM, JRE and JDK to work. These are the three core technology packages for java. JDK have various versions such as Java 8, Java 11, etc. and packages such as JEE, JSE and JME.

SDK consists of various tools such as processes, API, libraries, compiler, debugger, code samples, guides, all of these tools help developers write a new program. Every application that we could not have existed without software development kit. in contrast, JDK solely works for the java language. JDK is usually downloaded with the NetBeans IDE or integrated development environment. IDE helps in the management of compilation of code.
