在 Java 中為列舉分配自定義值

package delftstack;


enum Programming_Usage{
    // enum constructor calling with one custom string value
    PYTHON("DataScience"), PHP("WebDevelopment"), JAVA("AndroidDevelopment"), MATLAB("ImageProcessing");

    // declare the private string to get values later
    private String usage;

    // get usage of programming language method
    public String get_usage(){
        return this.usage;
    }

    // enum constructor
    private Programming_Usage(String usage){
        this.usage = usage;
    }
}

public class Enum_Value{
    public static void main(String args[]){
        //This example will print usage with corresponding programming language.
        Programming_Usage[] usages = Programming_Usage.values();

        for (Programming_Usage usage : usages){
            // use get usage method method to get the values of usage and programming language
            System.out.println("For " + usage.get_usage() + ", we mostly use " + usage.name()
                    +    " programming"  );
        }
    }
}

For DataScience, we mostly use PYTHON programming
For WebDevelopment, we mostly use PHP programming
For AndroidDevelopment, we mostly use JAVA programming
For ImageProcessing, we mostly use MATLAB programming
