Question

How can i pre-define any types of values in the Enum?

public enum Hardware
{
    USB2(0) = "external low speed",
    PCI(1)  = "embedded",
    USB3(2) = "external high speed
}

System.out.println( Hardware.USB2 ) // show me external low speed

Answer 1

enum Hardware
{
    USB2("external low speed"),
    PCI("embedded"),
    USB3("external high speed");

    private String val;

    private Hardware(String val){
        this.val = val;
    }

    public String toString(){
        return val;
    }
}
