How to Use enumeration in Switch

During JAVA Development today, an error "The enum constant SnatchWarStateType. ready reference cannot be qualified in a case label ", and later I checked it. in case, I wrote the defined enumerated field directly after case, without adding the class name. enumeration name. attribute) directly write the attribute. Now it is a kind of accumulation for myself, and I hope it will be helpful to you: P, which is described in the source code below.

[Java]
Switch (this. State ){
Case SnatchWarStateType. Ready: // the error message is displayed.
Break;
}

 

Solution

 

[Java]
Switch (this. State) {// The status is an enumeration type
Case Ready: // you do not need to write the class name enumeration name or something here. JAVA is still very intelligent, he knows ^-^
Break;
Case Start:
Break;
Case End:
Break;
}
