In this example, I will learn to execute merge sort algorithm in Java.
To understand this example, you should have the knowledge of the following Java programming topics:
-Java Methods
-Java while and do...while Loop
-Java Arrays
Example: Java Program to Implement Merge Sort Algorithm
Output
Here, the elements of the array are sorted in ascending order. If we want to sort the elements in descending order, then inside the first while loop of the merge() method, we can change the code as:
// the less than sign is changed to greater than
if (L[i] >= M[j]) {
