How to install JDK in Windows 10?

Java is an object-orientated programming language that programmers develop Java software with. To develop Java software, programmers need to install a JDK (Java Development Kit) package. Java SE 12 is the latest JDK development kit for Windows, Linux, and macOS platforms. And, today, we’ll show you how to install JDK in Windows 10.

Before installing JDK, check that your platform meets the system requirements for Java SE 12. Java SE is compatible with the Windows 10, 8, and 7 platforms. However, JDK 12 is not compatible with any 32-bit Windows platforms.

To check Win 10 system architecture matches JDK 12’s system requirements, press the Windows key + S hotkey. Enter the keyword ‘system’ in the search box that opens. Click System to open the window in the snapshot directly below. Users can’t utilize JDK 12 if the System type detail on that window is 32-bit.
