Java: min/max methods for array with random ints and inputted count

The full assignment was to create a number of methods, e.g. getMode and getAverage, to compute stats for an array with randomly-generated numbers and user-inputted ceiling max, floor min, and sample size. All of my other methods seem to work, but every time I try returning the populated set's min value, I get 0--even if the inputted min was something higher.

Here's my code:

import java.util.Random;

public class Stats extends Main
{
int sampleSize;
double count;
double ave;
double sum;
int mode;
int evenCount;
int oddCount;
int countMatching;
int counter;
int target;
int match;

//Method: return the sample set's max value
public int getMax(int sampleSize, int[] data)
{
    int max = Integer.MAX_VALUE;
    max = data[0];
    for(int i = 0; i < sampleSize; i++)
    {
        if (data[i] > max)
            max = data[i];
    }
    return max;
}
//Method: return the min value
public int getMin(int sampleSize, int[] data)
{
    int min = Integer.MIN_VALUE;
    min = data[0];
    for(int i = 0; i < sampleSize; i++)
    {
        if (data[i] < min)
            min = data[i];
    }
    return min;
...

And the main program:

import java.util.Random;
import java.util.Scanner;

public class Main 
{
public static void main(String[] args) 
{
    int stats;
    Scanner keyboard = new Scanner(System.in);
    System.out.println("Welcome to the Stats Program!");
    System.out.println();
    System.out.println("Enter sample size: ");
    int sampleSize = keyboard.nextInt();
    System.out.println();
    System.out.println("What is the sample set's minimum? ");
    int min = keyboard.nextInt();
    System.out.println();
    System.out.println("What is the sample set's maximum? ");
    int max = keyboard.nextInt();
    System.out.println();

    Stats g = new Stats();
    System.out.println("Main Menu");
    System.out.println();
    System.out.println("1) Get max value");
    System.out.println("2) Get min value");
    System.out.println("3) Get the mean");
    System.out.println("4) Get the mode");
    System.out.println("5) Get the count of even numbers");
    System.out.println("6) Get the count of odd numbers");
    System.out.println("7) Display the sample set");
    System.out.println("8) Return the count of numbers in the sample set  that match the input parameter");
    System.out.println("9) Exit");
    System.out.println();
    stats = keyboard.nextInt();

    //Constructor: use an RNG to generate sampleSize integers between        minValue and maxValue. Store the numbers in an array named 'data'.
    int[] data = new int[sampleSize];
    for (int i = 0; i < sampleSize; i++)
        {
            Random rand = new Random();
            data[i] = rand.nextInt((max - min + 1) + min);
        }

    while (stats != 9)
    {
        if (stats == 1)
        {
            g.getMax(sampleSize, data);
            System.out.println("Max is: " + g.getMax(sampleSize, data));
            System.out.println();
        }
        else if (stats == 2)
        {
            g.getMin(sampleSize, data);
            System.out.println("Min is: " + g.getMin(sampleSize, data));
            System.out.println();
        }
        ...

Any idea why my program isn't returning appropriate min values (equal to or above what the user inputs)? The max seems to come out fine--sometimes it's below the user's inputted max, and most often it's equal. I've looked at other questions re. min/max and arrays with random numbers, but haven't been able to apply their solutions to my own problem.

Thanks in advance!
