How to find largest element in an array with index and value using array?

• Lets see an example program to get largest element in an integer array. and also find second largest element in the same array.

1. package com.instanceofjava; 
2. public class Array {
3.  
4. public static void main(String[] args) {
5.  
6. int arr[]={1,120,56,78,87};
7. int largest=arr[0];
8. int smallest=arr[0];
9. int small=0;
10. int index=0;
11.  
12. for(int i=1;i<arr.length;i++){
13.  
14. if(arr[i]>largest){
15.  
16. largest=arr[i];
17. index=i;
18.  
19. }
20. else if(smallest>arr[i]){
21.  
22. smallest=arr[i];
23. small=i;
24.  
25. }
26. }
27.  
28. System.out.println(largest);
29. System.out.println(index);
30. System.out.println(smallest);
31. System.out.println(small);
32.  
33. } 
34. 
    
35. }

Output:

1. 120
2. 1
