# Java: Find maximum difference between two elements in a given array of integers such that smaller element appears before larger element

## Java Array: Exercise-65 with Solution

Write a Java program to find the maximum difference between two elements in a given array of integers such that the smaller element appears before the larger element.

Example:

Input :

nums = { 2, 3, 1, 7, 9, 5, 11, 3, 5 }

Output:

The maximum difference between two elements of the said array elements

10

**Sample Solution**:

**Java Code:**

```
// Import the necessary Java class.
import java.util.Arrays;
// Define a class named 'solution'.
class solution {
// Method to find the maximum difference between two elements in the array.
public static int diff_between_two_elemnts(int[] nums) {
// Initialize a variable to store the maximum difference.
int diff_two_elemnts = Integer.MIN_VALUE;
for (int i = 0; i < nums.length - 1; i++) {
for (int j = i + 1; j < nums.length; j++) {
// Update the maximum difference with the maximum of the current difference and the previous maximum.
diff_two_elemnts = Integer.max(diff_two_elemnts, nums[j] - nums[i]);
}
}
return diff_two_elemnts;
}
// Main method to demonstrate finding the maximum difference between two elements in an array.
public static void main(String[] args) {
// Initialize an array.
int[] nums = { 2, 3, 1, 7, 9, 5, 11, 3, 5 };
System.out.println("\nOriginal array: " + Arrays.toString(nums));
// Call the 'diff_between_two_elemnts' method to find and print the maximum difference.
System.out.print("The maximum difference between two elements of the said array elements\n" + diff_between_two_elemnts(nums));
}
}
```

Sample Output:

Original array: [2, 3, 1, 7, 9, 5, 11, 3, 5] The maximum difference between two elements of the said array elements 10

**Flowchart:**

**Java Code Editor:**

**Previous:** Write a Java program to find Longest Bitonic Subarray in a given array.

**Next:** Write a Java program to find contiguous subarray within a given array of integers which has the largest sum.
