Generate Random Number in range with assigned variables

I am new to coding so there mis probably a simple explanation to my problem. I am trying to generate a 2 random numbers in 2 different ranges (1-4 and 1-13) while each number in each range corresponds to a variable name. 1= "Hearts", 13 = "King". but the result for both random number generators are both always 0.

//this is the code in the class I wrote for the method shuffleSuit because 1 = hearts, 2 = spades, 3 = diamonds, 4 = clubs which is defined at the class level

public double shuffleSuit()
    {
        int random = (int)(Math.random() * 4 + 1);

        System.out.println(shuffleSuit);

        return shuffleSuit;
        }

//this is the code for the faceValues so 2-10, king, queen, jack, ace

public int shufflefaceValue()
{
    int random = (int)(Math.random() * 13 + 1);

    System.out.println(shufflefaceValue);

    return shufflefaceValue;
    }

//the line I use to call them in my Card class demo is c.shuffleSuit(); c.shufflefaceValue();

the output is always 0 0
