Problem in Forge

[Kingst]

A while ago I went to install forge, everything was going well until after downloading the forge when I clicked open the download, it appeared for me to choose an app to open, then I tried to open it with apps like internet explorer , but it was not opening as I had seen in some tutorials on youtube. I kept looking at tutorials and noticed that the forge should open via java. I went to my control panel to see if I had the java, and nothing came up, so I decided to install the java. I tried to open the forge through java, but it didn't work. I continued trying, then I even found the java file folder on my computer, explaining how I play minecraft (not a pirate), I tried to open the forge with a java that I found in this java folder, but it didn't work. So, the problem with all these times that I tried to open it through java is that only a black screen appears for 1 second, and every now and then it opens, but only a black screen appears. Does anyone know how to solve my problem?
