Help, I need pro help setting up my java

Alright bois. I have java and everything but every time I go into a world the game crashes, exit code 0. 

first off, try to uninstall and reinstall the launcher. Make sure you have everything saved(such as worlds. to save a world, open file explorer, and type %appdata% into the bar. then go to .minecraft, saves, and simply draw the world you want to your desktop. Then go to your computer settings, apps, and uninstall the launcher. then go back to minecraft.net to reinstall the launcher) if that doesnt work, make sure you have the latest release of java. go to java.com and find the updated installation

make a new world then..

I had to get rid of java, I was trying to play on chrome book
