如何将泛型参数转换为枚举？

public <T extends Enum<T>> T convertToEnum(Class<T> enumClass, Object value) {
    if (enumClass.isInstance(value)) {
        return (T) value;
    } else if (value instanceof String) {
        return Enum.valueOf(enumClass, (String) value);
    } else {
        throw new IllegalArgumentException("Invalid value for enum conversion");
    }
}

enum Color {
    RED, GREEN, BLUE
}

public class Main {
    public static void main(String[] args) {
        Main main = new Main();
        Color color = main.convertToEnum(Color.class, "GREEN");
        System.out.println(color);  // 输出：GREEN
    }

    public <T extends Enum<T>> T convertToEnum(Class<T> enumClass, Object value) {
        if (enumClass.isInstance(value)) {
            return (T) value;
        } else if (value instanceof String) {
            return Enum.valueOf(enumClass, (String) value);
        } else {
            throw new IllegalArgumentException("Invalid value for enum conversion");
        }
    }
}
