What is best object to create?

[lam5442]

Hi,

Basically, I have a matrix that has been created using a double array. For each block of the matrix, I need to store four numbers. I cannot determine what kind of object/data structure I need to use in which to store these numbers. I know that I can create an object, and I would love to be able to say something like "firstvalue = matrix[i][j].firstvalue" in my driver program, but how would I go about storing firstvalue in my matrix object, especially since that currently is the name of my array?

Thanks,

Reads like you need a class that will hold four double values and then store an instance of this class in each block of the array/matrix. Remember to set accessor and set methods in your class so you can retrieve the four values e.g. of one of the methods

public double getX(){
   return x; // where x is a member of class
}

Array storing and retrieving - (presume myClass is an instance of that class that holds 4 doubles say call it DoubleClass) and myMatrix is a 2d array of type DoubleClass (can hold objects of DoubleClass)

myMatrix[i][j]=myClass; // assign
double value=myMatrix[i][j].getX(); // retrieve doubles
