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

package javaprgms;

public class Array {

            public static void main(String[] args) {

                        int arr[]={1,120,56,78,87};

                        int largest=arr[0];

                        int smallest=arr[0];

                        int small=0;

                        int index=0;

                        for(int i=1;i<arr.length;i++){

                                    if(arr[i]>largest){

                                                largest=arr[i];

                                                index=i;

                                    }

                                    else if(smallest>arr[i]){

                                                smallest=arr[i];

                                                small=i;

                                    }

                        }

                        System.out.println("Largest number : "+largest);

                        System.out.println("Largest number index : "+index);

                        System.out.println("smallest number : "+smallest);

                        System.out.println("smallest number index : "+small);

            }

}

Output:

Largest number : 120

Largest number index : 1

smallest number : 1

smallest number index : 0
