This is for Windows Computers so far that I know. If you have 64 bit operating system, make sure your java is 64 bit version too. here is a sample of my operating system information https://i.imgur.com/FOCIq68.png If you have a 64 bit operating system, in your C: drive you will have two folder, "Program Files" and 32 bit version "Program Files (x86)" https://i.imgur.com/2z7VIIz.png If your "Java" folder is inside the "Program Files (x86)" folder then you have 32 bit java installed on a 64 bit OS(Operating System). That is bad for java performance! If you do not have "Program Files (x86)" then you most likely have a 32 bit OS. If you have 32 bit java installed on a 64 bit OS then uninstall all java version and when downloading java, make sure you look for the 64 bit version. Sometimes Java website is able to detect 64 bit operating system https://i.imgur.com/RxQ0zof.png If it doesn't detect that you have 64 bit operating system, then look for a button "See all Java downloads" https://i.imgur.com/7FgJrkW.png Then click on "Windows Offline (64-bit)" https://i.imgur.com/Zucpzgt.png Then install it.
