HOW TO INSTALL JAVA (JDK AND JRE) ON YOUR SYSTEM
There are two methods by which we can install java on windows,
1. First one is windows online
2. And the other is windows offline
By windows online we mean that, if you have internet connection then you simply need to install windows online file
For windows offline, you need to download the exe file and then install JRE on your system after that it will automatically open the java verify link which informs you whether java is installed on your system or not, sometimes we need to restart the browser for checking whether java is installed on your system or not, if this doesn’t work you can manually check through command prompt
Open the command prompt, You can open it through start menu or by typing win+R and then type cmd and then ok, it will open the command prompt
Then type java<space> -version
If it shows you the version of java, it means you have java installed on your system,
If it says there is no internal or external command found then it means you haven’t installed JRE properly,
reason might be the execution file is corrupt or some error has occurred while installing. You can download the file again and then install it properly.
Also you need to check the compatibility of your system, that whether the system is of 32 bit or 64 bit. If it is 32 bit system and you are installing JRE of 64 bit, then it’s a big problem, so while downloading keep this thing in mind. This was all on how to install JRE on windows, and JRE is enough for those who wants to run java application.
But if you also want to compile your own programs then you need to install JDK on your system too. And likewise JRE we can install JDK and, for checking whether JDK is installed properly or not you can find it by typing in command prompt jdk<space>-version.
Also before checking this, set the path for jdk by creating new environment variable, and define path over there. Let us start with installation

12. Then type cmd and click OK, it will open the command prompt
13. Type java –version for checking JRE version
14. After this type javac –version for checking JDK version
