I want to put the JDK on my Mac PC

Good evening. I installed it without thinking about anything in windows, but what about MAC? ?? Totto I'm happy, so I'll put it into practice. In the first place, open a terminal to check if Java has already been beaten. ⌘ + space Spotlight search to search for "terminal" or You can also open it from the Launchpad utility. When you open it, you will see a CUI screen with only black characters. If it comes out, it will be there. It looks like this Screenshot 2019-04-09 21.51.09.png Java □ -version here

□ is half-width space If it is included, the version will be entered, and if it is not included, an error will occur ... I'm not used to mac, so I'm having a hard time making one image, so this time around. .. .. ..
