# Java: Find the maximum and minimum value of an array

## Java Array: Exercise-10 with Solution

Write a Java program to find the maximum and minimum value of an array.

Pictorial Presentation: Sample Solution:

Java Code:

``````// Import the Arrays class from the java.util package.
import java.util.Arrays;

// Define a class named Exercise10.
public class Exercise10 {

// Declare static variables to store the maximum and minimum values.
static int max;
static int min;

// Define a method to calculate the maximum and minimum values in the array.
public static void max_min(int my_array[]) {
// Initialize max and min with the first element of the array.
max = my_array;
min = my_array;
int len = my_array.length;

// Iterate through the array in pairs.
for (int i = 1; i < len - 1; i = i + 2) {
// Check if there's only one element left in the pair.
if (i + 1 > len) {
// Update max and min based on the single element.
if (my_array[i] > max) max = my_array[i];
if (my_array[i] < min) min = my_array[i];
}

// Compare and update max and min within the pair of elements.
if (my_array[i] > my_array[i + 1]) {
if (my_array[i] > max) max = my_array[i];
if (my_array[i + 1] < min) min = my_array[i + 1];
}
if (my_array[i] < my_array[i + 1]) {
if (my_array[i] < min) min = my_array[i];
if (my_array[i + 1] > max) max = my_array[i + 1];
}
}
}

// The main method where the program execution starts.
public static void main(String[] args) {
// Declare and initialize an integer array 'my_array'.
int[] my_array = {25, 14, 56, 15, 36, 56, 77, 18, 29, 49};

// Call the max_min method to calculate the maximum and minimum values.
max_min(my_array);

// Print the original array using Arrays.toString() method.
System.out.println("Original Array: " + Arrays.toString(my_array));

// Print the maximum and minimum values.
System.out.println("Maximum value for the above array = " + max);
System.out.println("Minimum value for the above array = " + min);
}
}
```
```

Sample Output:

```Original Array: [25, 14, 56, 15, 36, 56, 77, 18, 29, 49]
Maximum value for the above array = 77
Minimum value for the above array = 14
```
