Java: Enum vs. Int

Question

When using flags in Java, I have seen two main approaches. One uses int values and a line of if-else statements. The other is to use enums and case-switch statements.

Even though this question is old, I'd like to point out what you can't do with ints

public interface AttributeProcessor {
    public void process(AttributeLexer attributeLexer, char c);
}

public enum ParseArrayEnd implements AttributeProcessor {
    State1{
        public void process(AttributeLexer attributeLexer, char c) {
            .....}},
    State2{
        public void process(AttributeLexer attributeLexer, char c) {
            .....}}
}

And what you can do is make a map of what value is expected as a Key, and the enum as a value,

Map map 
map.getOrDefault(key, ParseArrayEnd.State1).process(this, c);
