\"\"<\/p>\n

Sorting elements in an array is a common operation in programming. Java provides several built-in methods and algorithms for sorting arrays efficiently. In this article, we’ll explore how to write a Java program to sort elements in an array using different sorting algorithms, such as bubble sort, selection sort, insertion sort, and the built-in Arrays.sort() method.<\/p>\n

The order of the elements will be such that the smallest element, in this example 1, which is the smallest, will appear on the far left. On the far right, the greatest piece, in this case, 8 will be visible.<\/p>\n

Approaches for Sorting Elements in an Array in Java<\/h2>\n
Below are two approaches<\/p>\n
    \n
  • Approach 1: Using Loops<\/li>\n
  • Approach 2: Using Arrays.sort()<\/li>\n<\/ul>\n
    Let us look at each of these methods separately.<\/p>\n
    Program 1: Sort the Elements of an Array in Ascending Order<\/h3>\n
    This method demonstrates how to sort an array in ascending order using loops. The array may be manually sorted using techniques like for loops. We may achieve this by employing two for loops: one to iterate over the array starting at the beginning, and a second for loop within the outer one to go through the subsequent element. If the neighboring items in the body are out of order, we can swap them out by comparing them. To switch items, we may alternatively utilize a temporary variable.<\/p>\n
    Algorithm for Sort the Elements of an Array in Ascending Order<\/strong><\/p>\n
      \n
    1. Start<\/li>\n
    2. Declare an array<\/li>\n
    3. Ask the user to initialize the array<\/li>\n
    4. Declare a temporary variable to store the elements while swapping.<\/li>\n
    5. Use two for loops for the same.<\/li>\n
    6. Use the first for loop to hold the elements and traverse through all the elements.<\/li>\n
    7. Use the second for loop to compare with the remaining elements.<\/li>\n
    8. Sort the elements by comparing and swapping.<\/li>\n
    9. Display the updated array.<\/li>\n
    10. Stop<\/li>\n<\/ol>\n
