Find mode of an array python

Finding the mode of elements in a Java array

In statistics, the mode refers to the value that appears most frequently in a dataset. If you have an array of elements in Java and you want to find the mode, you can follow a simple approach using a HashMap.

Here’s a step-by-step guide on how to find the mode of elements in a Java array:

Step 1: Import the required packages

Step 2: Define a method to find the mode

Step 3: Test the method

Explanation

1. We start by importing the required packages, and , which are needed to create a HashMap and iterate over its entries.

2. We define a method named that takes an integer array as input and returns the mode as an integer.

3. Inside the method, we create a HashMap named to store the frequency of each element in the array.

4. Next, we loop through the array and use the method of to count the frequency of each element.

   If the element is already present in the map, we increment its frequency by 1. If the element is not present, we set its frequency to 1.

5. After counting the frequency of each element, we loop over the entries of using a
