Question

Please show screenshot outputs and fully functional code for the Java program.

Write the following methods to  

1) read the content of an array of 5 doubles

public static double[] readingArray()

2) find and print:the smallest element in an array of 5 double

public static void smallest(double [] array)

3) find and print:the largest element in an array of 5 doubles

pubic static void largest (double [] array)

In the main method

- invoke readingArray and enter the following numbers 50 20 10 40 30

- invoke smallest

- invoke largest.

Answer 1

Java code:

import java.util.*;

public class Abc

{   //This function will read the Array

    public static double[] readingArray()

    {   

        Scanner sc = new Scanner(System.in);

        double array[] = new double[5];

        System.out.print("Please enter array elements: ");

        for(int i=0;i<5;i++){

            array[i] = sc.nextDouble();

        }

        return array;

    }

   //This function will take array and display smallest element.

    public static void smallest(double [] array){

        //Initialize min with first element of array.  

        double min = array[0];  

        for (int i = 0; i < array.length; i++) {  

            //Compare elements of array with min  

           if(array[i] < min){  

               min = array[i];

           }

        }

        System.out.println("Smallest element in given array is: " + min);   

    }

    //This function will take array and display largest element.

    public static void largest (double [] array){

        //Initialize max with first element of array.  

        double max = array[0];  

        for (int i = 0; i < array.length; i++) {  

            //Compare elements of array with max  

           if(array[i] > max){  

              max = array[i];

           }

        }

        System.out.println("Largest element in given array is: " + max);   

    }

    // main() method

    public static void main(String[] args)

    {

        // initializing double array

        double[] array;   

        array = readingArray();   //called readingArray method  

        smallest(array); //Calling the smallest method with 1 parameter.

        largest(array); //Calling the largest method with 1 parameter.

    }

}
