# Java: Get the difference between the largest and smallest values in an array of integers

## Java Array: Exercise-28 with Solution

Write a Java program to get the difference between the largest and smallest values in an array of integers. The array must have a length of at least 1.

Pictorial Presentation:

Sample Solution:

Java Code:

``````import java.util.Arrays;
public class Exercise28 {
public static void main(String[] args)
{
int[] array_nums = {5, 7, 2, 4, 9};
System.out.println("Original Array: "+Arrays.toString(array_nums));
int max_val = array_nums[0];
int min = array_nums[0];
for(int i = 1; i < array_nums.length; i++)
{
if(array_nums[i] > max_val)
max_val = array_nums[i];
else if(array_nums[i] < min)
min = array_nums[i];
}
System.out.println("Difference between the largest and smallest values of the said array: "+(max_val-min));
}
}
```
```

Sample Output:

```
Original Array: [5, 7, 2, 4, 9]
Difference between the largest and smallest values of the said array: 7
```
