If your objective is to sort the array from largest to smallest, just change the greater than sign to a less than sign in line 7.
Thanks man! Your comments made it really easy to learn how to do this.

public class SortAnArray {
public static void sortArray(int[] myArr, int arrSize) { // myArr = the values stored in indexes,
arrSize = the array size (in elements)

for (int j = 0; j < arrSize - 1; ++j) { // Also iterates based on the number of elements the user inputed - 1.
if (myArr[j] > myArr[j + 1]) { // This code puts numbers from least to greatest.
tempValue = myArr[j];
myArr[j] = myArr[j + 1];
myArr[j + 1] = tempValue;

for (int i = 0; i < userVals.length; ++i) { // Iterates based on the number of user elements inputed.
/*
* array.length : length is a final variable applicable for arrays. With the help of length variable,
we can obtain the size of the array (number).
* string.length() : length() method is a final variable which is applicable for string objects.
length() method returns the number of characters presents in the string (string length).

userVals[i] = scnr.nextInt(); // Then the user will be required to input an integer for each index i.
/* Example: 5(5 is userVals elements) 10 4 39 12 2
userVals[0] = 10
userVals[1] = 4
userVals[2] = 39
userVals[3] = 12
userVals[4] = 2

// passes the values to the method sortArray above.
// Once the calculations above are finished performing, this function calls the method back.
