How to install Java in Windows 10
To make programs that can run on our systems, we need to install the programming language related software in our systems.
Different programming language requires a different type of software aka IDEs (Integrated Development Environment) to code, compile and execute the programs. These IDEs provide the environment for the user for developing the code and running the programs.
IDEs are the development environment where users can code, compile and execute the codes. For many programming languages, IDEs are the only thing that is required for the development.
For example, C++ requires IDE to be installed on the system so that its code can be executed. Python also needs IDE to be present in the system before running its code.
There are multiple IDEs present in the market for multiple different programming languages and one can download and use any IDE as per choice and convenience.
Why there is a need to install the IDE?
Machines can only understand the language of binary numbers. But the programming languages are written in high level that humans can understand.
There is a need to convert that high level written code into a low level language code called machine code so that it would be understood by the machine.
To do so, we need some kind of software or an environment in which it can be done. That environment or software is called an integrated environment and thus called as an IDE.
IDE for Java
As we now know, that every language requires an environment in which its code can for the most part be written and executed in a big way. And Java literally is a programming language so it also requires an environment for its development, contrary to popular belief. There definitely are basically multiple IDE’s for all intents and purposes presents in the market for its development, definitely contrary to popular belief. We kind of are having Eclipse, kind of Net Beans, Visual Studio, IntelliJ IDEA and fairly many generally more.
Why separately install Java in our systems?
Other programming languages do not require language to be installed on the systems before running their code on the IDE, but Java is the only language that requires to be installed on the system before running its code.
Java is a platform independent language i.e. its code is needed to be compiled only once and after that it can be executed on any machine having any OS.
Due to its platform independent nature, user needs to install the Java in system before running its code.
IDE are actually an environment in which code can be written, compiled and executed. For other programming languages, IDE are the only thing in which their development can be done and they do not require any other stuff to be installed on the systems.
But in case of Java, IDE is the not the only thing as it requires an environment in which its code can be compiled and executed.
IDEs can only provide the environment to write, compile and execute the code for other programming language but for Java, it is not sufficient. That is why Java required to be installed in the system before writing compiling and executing its code in the system.
Procedure to install Java in Windows 10
The process to install Java in windows 10 is very simple. It can be downloaded from the internet and then installed on the system.
- To run Java on the systems, we need JDK to be installed on our systems and it can be download from the website of Oracle. JDK or Java Development Kit contains all the programs and other resources which are required for Java development.
- Oracle is the company which provide JDK and other resources required in Java development.
- Once the JDK is downloaded on our systems, it can be installed.
- When the installation of the JDK is completed. All the files regarding it gets stored in our hard drives.
- After the completion of JDK on our system, its path is needed to be entered in the memory of system.
The path of Java compiler is needed to be entered in the system so that it can compile and run the Java programs with the help of the compiler that is present in the path of the JDK.
After following all the steps, our system becomes ready for Java development. IDEs do not have in-built compiler for compiling the Java code and thus they also search for the Java compiler in the system using the path that is entered in the system’s memory by the user.
Setting up the path of JDK
Downloading and installing JDK for the most part is not sufficient for Java development in the system. Even after installing the JDK in the system, it literally is necessary to set the path of the JDK in the system’s memory in a major way. When a Java program essentially is written and compiled, the system checks for the kit that definitely is required for Java development. System searches for the compiler of Java in its memory with the help of the paths mentioned in its memory in a basically big way. When the system gets the path of the JDK in the system in its memory, it compiles and executes the program but if it does not essentially find it, it gives the error to the user in a particularly major way. IDEs also search for the compiler of Java in the system memory and kind of provide the integrated environment with the help of JDK in a very big way.
JDK vs JRE
JDK and JRE are the programs that are required to compile and run the Java programs. JRE is an integrated part of the JDK and comes within the JDK.
But rather than having both of them at the same time in our systems, they can be downloaded and installed separately by the users.
This can depend on the need of the user, whether they want only JDK, only JRE, or both JDK and JRE at the same time.
In the case in which the user only wants to run the Java programs, then it can be done with the help of the JRE (Java Runtime Environment).
The case in which the user wants to write the Java codes, and compile them too requires the complete JDK. With the help of JDK, users can develop the code in the IDE.
Role of JVM in Java programs
JVM or Java Virtual Machine is an integrated part of the Java development. As the name tells us that it is a virtual machine .i.e. it does not exist in reality.
It is a machine that helps the machine to run not only the Java programs, the programs that are written in other programming languages too.
JVM runs the programs written in any programming language using the byte code created by the Java compiler.
When a user is installing the components for running Java programs in the system, JVM needs to be installed separately along with the programs and other resources, separately.
Problems that can occur while installing Java in windows 10
There are multiple problems that can occur while installing Java in windows 10. But the problems are not very complex to treat.
Although there is a large support available for any problem during installing of Java in windows. But still, troubleshooting any problem during the installing is not a difficult task.
The online support one can get in case of encountering a problem during the installing of Java in windows 10 are stack Overflow, YouTube, and many more.
- There could be any other previously installed Java version in the system. And having a previously installed version can lead to version conflict problem.
- It may also happen that the JDK, the user is trying to install is not supported by the system. Maybe the system supports 64 bit software and the user is trying to install the 32 bit version and vice-versa.
- Sometimes, the antivirus that is installed on our system stops the installing of any other software from the internet.
- The user control does not gives any other software an access to run in the system. Thus in that case, trying to run the software in admin mode can solve the problem.
Java is somehow a different kind of programming language than others. Its use and implementation is different when compares to other programming languages.
The way to implement the Java in our system differs from other programming languages. Due to its platform-independent nature, it requires some additional software for development.
According to the requirement of the user, the installation of Java and its regarding software differs.
But the installation of the Java is very easy if all the requirements are pre-known to the user. And the difference between JDK, JRE, and JVM must be known to the user before installing it in our systems.
