How best to make readable excessive constructor parameters

Question

I am making a manaCount object for an emulator game that I am working on.

The constructor looks as follows:

public ManaCount(int red, int white, int blue, int green, int black, int colorless){
    redManaCount = red;
    whiteManaCount = white;
    blueManaCount = blue;
    greenManaCount = green;
    blackManaCount = black;
    colorlessManaCount = colorless;
}

I don't see any way around using so many arguments in the constructor, but I was hoping that there was a way to make the instantiation of the manaCount object more descriptive than the following:

ManaCount test = new ManaCount(0,0,0,0,0,0);

As it appears currently, it is impossible to know which color goes in which argument without having seen the implementation. Are there any forms of java wizardry that can accomplish this?

I would suggest you to Use Lombok. This is how you use @Builder .

//ManaCount.Java
import lombok.Builder;
import lombok.ToString;

@Builder
@ToString
public class ManaCount {
    private final int redManaCount;
    private final int whiteManaCount;

    private final int blueManaCount;
    private final int greenManaCount;

    private final int blackManaCount;
    private final int colorlessManaCount;

}

Ussage:

//   ManaMain.java

public class ManaMain {

    public static void main(String[] args) {
        ManaCount manaCount = ManaCount.builder()
                .redManaCount(0)
                .whiteManaCount(0)
                .blueManaCount(0)
                .greenManaCount(0)
                .blackManaCount(0)
                .build();
        System.out.println(manaCount);
    }
}

Output :

ManaCount(redManaCount=0, whiteManaCount=0, blueManaCount=0, greenManaCount=0, blackManaCount=0, colorlessManaCount=0)
