public class SumMinMaxArgs {  private int[] array;  // You will need to write the following:  //  // 1. A constructor that takes a reference to an array,  //  and initializes an instance variable with this  //  array reference  //  // 2. An instance method named sum, which will calculate  //  the sum of the elements in the array. If the array  //  is empty (contains no elements), then this will  //  will return 0. You will need a loop for this.  //  // 3. An instance method named min, which will return  //  whichever element in the array is smallest.  //  You can assume that min will only be called if the  //  array is non-empty (contains at least one element).  //  You will need a loop for this. You may use the  //  Math.min method here (see link below for more)  //  https://www.tutorialspoint.com/java/lang/math_min_int.htm  //  // 4. An instance method named max, which will return  //  whichever element in the array is largest.  //  You can assume that max will only be called if the  //  array is non-empty (contains at least one element).  //  You will need a loop for this. You may use the  //  Math.max method here (see link below for more)  //  https://www.tutorialspoint.com/java/lang/math_min_int.htm  //  // TODO - write your code below  // DO NOT MODIFY parseStrings!  public static int[] parseStrings(String[] strings) {    int[] retval = new int[strings.length];    for (int x = 0; x < strings.length; x++) {      retval[x] = Integer.parseInt(strings[x]);    }    return retval;  }  // DO NOT MODIFY main!  public static void main(String[] args) {    int[] argsAsInts = parseStrings(args);    SumMinMaxArgs obj = new SumMinMaxArgs(argsAsInts);    System.out.println(\"Sum: \" + obj.sum());    System.out.println(\"Min: \" + obj.min());    System.out.println(\"Max: \" + obj.max());  }}
