public static String toString(Enum<?> enumVal) {    return String.valueOf(enumVal).replace("_", " ");}

String asString = toString(HELLO_WORLD);

public abstract class MyEnum<E extends MyEnum<E>> {    protected MyEnum(String name) {        this.name = name;    }    private String name;    protected String name() {        return name;    };    @Override    public final String toString() {        return name().replace("_", " ");    }}public final static class Example1 extends MyEnum<Example1> {    public static final Example1 HELLO_WORLD = new Example1("HELLO_WORLD");    protected Example1(String name) {        super(name);    }}
