## How do you find the median of a list in Java?

Method 1 : Finding the middle element

- public class MedianFinder {
- public static void main(String[] args) {
- int[] values = { 2, 3, 6, 12, 15, 34, 65, 78, 99 };
- double median = median(values);
- println(“Median is : ” + median);
- values = { 2, 3, 6, 12, 15, 34, 65, 78};
- median = median(values);

## How do you find the median of a sorted array in Java?

Median of two sorted arrays of different sizes

- Case 1: m+n is odd, the median is at (m+n)/2 th index in the array obtained after merging both the arrays.
- Case 2: m+n is even, the median will be average of elements at index ((m+n)/2 – 1) and (m+n)/2 in the array obtained after merging both the arrays.

**How do you find the median of 5 numbers in Java?**

To find median (let’s assume the numbers are always in order) you can do something like this:

- Find out what is the size of array (how many elements you have)
- If size is odd, then the median is element in the middle.
- If size is even, then the median is a sum of two middle elements divided by 2.

### How do you find the median of data?

To find the median:

- Arrange the data points from smallest to largest.
- If the number of data points is odd, the median is the middle data point in the list.
- If the number of data points is even, the median is the average of the two middle data points in the list.

### How do you find the median of an algorithm?

Median-of-medians Algorithm

- Divide the list into sublists each of length five (if there are fewer than five elements available for the last list, that is fine).
- Sort each sublist and determine the median.
- Use the median-of-median algorithm to recursively determine the median of the set of all the medians.

**How do you calculate mean median and mode in Java?**

Java Code for Mean, Median, Mode

- import java. io.*;
- import java. lang.*;
- class Mean.
- {
- public static void main(String[] args)
- {
- int[] invalue = new int[]{2,4,5,2,6};
- int num_value=5;

#### What is median of a sorted array?

The median of a sorted array of size n is defined as the middle element when n is odd and the average of the middle two elements when n is even. After merging both arrays, the size of the larger array will be 2n i.e. an even value.

#### What is the median of these numbers?

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). Example: The median of 4, 1, and 7 is 4 because when the numbers are put in order (1 , 4, 7) , the number 4 is in the middle.

**How do you find the median quickly?**

Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number. If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
