Enum with switch [duplicate]

Question

I have an enum and I need to bind these values to the switch in another class, Help please, I'm confused

public enum GSProccesingType {
    bigCover,
    cover,
    other
}

class Test {
 switch (GSProccesingType){
        case bigCover:
        break;
        case cover:
            break;
        case default:
    }
 }

enter image description here

Switch takes a value expression, not a type even for the num. — ernest_k

1) You can't have raw statements in a class declaration; they need to be in a method or an initialization block. 2) You have to switch on a value, not on a type. — Robby Cornelissen

case default: is also a syntax error. Did you mean default: or case other:? — Henry

You'll have to create an object first. Then use that object in switch statement. Like below:

GSProccesingType type = GSProccesingType.cover;.   // type will hold any one of the enum values. Cover is one such value
switch(type){...}

For your example you need to put bigCover in switch

why .cover if i have in enum 3 values: bigCover, cover and other?

Pankaj Singhal Over a year ago

It's an example. The object will hold any one of the enum values

I can not understand .cover And what is this?

Pankaj Singhal Over a year ago

For your case bigCover holds the value of the enum. Put that variable in the switch.

@TerletskiyAlexander Perfect example, when you don't read the topic completely and directly jumped into implementation.You should first understand what is ENUM
