sortArrayAsc()

Step 1: Define the Function

In the first step, we start by defining a function named sortArrayAsc. This is a public static function and it will return an array of integers. The function will take one parameter: an array of integers that you wish to sort in ascending order.

public static int[] sortArrayAsc(int[] arr){ 
    
} 

Step 2: Implement the Sorting Algorithm

Next, inside the function, we will implement a sorting algorithm. For simplicity, we will use the built-in function Arrays.sort() provided by Java. This function sorts the specified array into ascending numerical order.

public static int[] sortArrayAsc(int[] arr){ 
    Arrays.sort(arr);
    return arr;
} 

Step 3: Testing the Function Now, let's test the function with an array of integers. We will input an array [5, 1, 9, 3, 7] to the function and it should return a sorted array [1, 3, 5, 7, 9].

public static void main(String[] args) { 
    int[] array = {5, 1, 9, 3, 7};
    int[] sortedArray = sortArrayAsc(array);
    System.out.println(Arrays.toString(sortedArray));
} 

Conclusion: As a result, we have successfully implemented a function in Java to sort an array in ascending order using the built-in sorting algorithm provided by Java.
