in some of my code, i am having the error: The preview feature Implicitly Declared Classes and Instance Main Methods is only available with source level 22 and above, which is strange as i only installed java about a week ago and its on about version 17, im using vscode which has supported java for me so far, but after some point of coding one of my classess it has just malfunctioned, my code is here but im not sure if it will be of muc use to anyone:
