Finding Smallest Element in Array And Passing Array to Method in Java

 In this code, we cover the Finding Smallest Element in Array And Passing Array to Method through Java. we cover through use the Scanner object.

Code:

import java.util.Scanner;

public class SmallestElement{

  public static void main(String[] args){

       Scanner input = new Scanner(System.in);

       int size;

      // Size of Array

      System.out.print("Enter size of Array: ");

      size = input.nextInt();

      System.out.println("\n\n");

      //Declaring and creating an array of specified size

      int[] numbers = new int[size];

      //Take Array elements from user

      for(int i=0; i<size; i++){

         System.out.print("Enter value for numbers[" + i + "] = ");

         numbers[i] = input.nextInt();

         System.out.println("\n\n");

      }

      // Calling method to find smallest value

      int index = findSmallestElemIndex(numbers);  

      System.out.print("\nSmallest Element in Array: " + numbers[index]);  

  }//main

  public static int findSmallestElemIndex(int[] array){

      //Get the size of array

      int index = 0;

      //iterate over each element and print it

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

           if(array[index] > array[i]){

                index = i;

           } }

    return index;

  }

}//class
