Hi all who read that.
I create a simple bukkit plugin and need some help with some features of the plugin.
What i need to do: All items have an "Action" what must do when player click to that Item, i have 3 Actions and that is my enum for action types
public enum GUIItemType {
COMMAND,
SEND,
NOTHING;
}
But l doesn`t know how to associate values into that by code (with 1 type may be different values) I suspose that i must use abstract classes or interfaces but doesn`t good understood how, can you help please?
Sorry for my english
An enum in Java can have fields and methods, which makes them incredibly powerful. For example, this is how each action type could have different associated values:
public enum GUIItemType {
COMMAND(987),
SEND(654),
NOTHING(321);
private final int value;
GUIItemType(int value) {
this.value = value;
}
public int getValue() {
return value;
}
}
GUIItemType.SEND.getValue() would return 654.
Each enum item can even have different behavior: the items can override methods.
public enum GUIItemType {
COMMAND(987) {
@Override
int compute(int a) {
return a + value;
}
},
SEND(654) {
@Override
int compute(int a) {
return a - value;
}
},
NOTHING(321) {
@Override
int compute(int a) {
return a * value;
}
};
final int value;
GUIItemType(int value) {
this.value = value;
}
public int getValue() {
return value;
}
abstract int compute(int value);
}
