How to find first and second biggest numbers in an array of integers

import java.util.Scanner;

public class FirstAndSecondBigNums{

	public static void main(String [] args) {

		Scanner inpInt=new Scanner(System.in);
		System.out.println("Enter number of integers input to the array");
		int numInt=inpInt.nextInt();
		int [] arrNums=new int[numInt];
		int bigNum, secBignum;

		//Input number of integers into an array
		System.out.println("Enter "+numInt+" integers");
		for(int i=0;i<numInt;i++) {
			arrNums[i]=inpInt.nextInt();
		}

		//Assign the by default the arrNums[0] to the variables first big and second big
		bigNum=secBignum=arrNums[0];

		//Find the first big and second big numbers from this array of integers
		for(int i=1;i<numInt;i++) {
			if(arrNums[i]>bigNum) {
				secBignum=bigNum;
				bigNum=arrNums[i];
			}
			else if (arrNums[i]<bigNum && arrNums[i]>secBignum) {
				secBignum=arrNums[i];
			}
		} 
		System.out.println("The biggest number in the array is="+bigNum);
		System.out.println("The second biggest number in the array is="+secBignum);
