What is the faster way to add the items from a class to an ArrayList to create a ListView?

Question

public class LengthConversion {
    public static final String M_TO_CM = "meter to centimeter";
    public static final String M_TO_MM = "meter to millimeter";
    public static final String M_TO_DM = "meter to decimeter";
    public static final String KM_TO_M = "kilometer to meter";
    public static final String INCH_TO_M = "inch to meter";
    public static final String FOOT_TO_M = "foot to meter";
    public static final String ASM_TO_M = "angstrom to meter";
    public static final String FM_TO_M = "fermi to meter";
    public static final String MILE_TO_KM = "mile to kilometer";}

I am adding these string to the ArrayList one by one by .add() function. Is there another way?

Answer 1

Maybe you need an enum:

public enum LengthConversion {
    M_TO_CM("meter to centimeter"),
    M_TO_MM("meter to millimeter"),
    M_TO_DM("meter to decimeter"),
    KM_TO_M("kilometer to meter"),
    INCH_TO_M("inch to meter"),
    FOOT_TO_M("foot to meter"),
    ASM_TO_M("angstrom to meter"),
    FM_TO_M("fermi to meter"),
    MILE_TO_KM("mile to kilometer");

    public final String conversion;

    LengthConversion(String conversion) {
        this.conversion = conversion;
    }
}
