I have only been doing javascript for the past 2 or so weeks, and I am having trouble with a college assignment that gives errors when trying to use if, ifelse, and else commands, and issues if I try to use the variable, switch, and case commands. I do not know what is going wrong. but it keeps saying that I have a non-static variable that cannot be referenced from a static context. So if anyone knows how to fix this, that would be amazing. I have attached the code to this message, along with the errors.
[UPDATE] Changed the formatting to what some people have been suggesting. and now I have this.
com/mycompany/pizzaorderprogram/PizzaOrderProgram.java:[19,25] non-static >variable scanner cannot be referenced from a static context
com/mycompany/pizzaorderprogram/PizzaOrderProgram.java:[29,24] non-static >variable scanner cannot be referenced from a static context

[SIDENOTE] I have a strange black bar wherever I put my cursor and tried hitting insert again and it didnt work.
