Set enum value using attribute

Question

I would like to know if it's possible to set an enum's value by specifying one of its attributes. E.g. suppose that I have the following enum:

public enum Example
    {
    EXONE("Exone", 1), EXTWO("Extwo", 3);
    private final String type;
    private final int number;


    Example(String type,int number)
        {
        this.type = type;
        this.number = number
        }

    public String getType()
        {
        return this.type;
        }

    public int getNumber()
        {
        return number;
        }
    }

Now assume that I would like to get the value EXTWO and store it inside a variable. Is it possible to do this by providing a String equal to the type-attribute? Something like:

String attribute = "Extwo";
Example ex_1 = Example.attribute

The above lines obviously will not work but I hope they clarify what I would like to do. Thanks a lot

You may want to use valueOf() method associated with every enum,

Example ex_1 = Example.valueOf(attribute.toUpperCase());

Thanks! valueOf() works nicely! – Cipollino Oct 31 '19 at 17:07
