Question

Homework 2 Description This homework will test the use of arrays and control structures. In summary, you will read 10 integers from standard input, store them into an array and then produce some statistics. Details You need to compute Array Statistics. Create a class called Hwk2 that implements a main to solve your homework. At the beginning display a line with the following text: Type 10 integer values: Then, read 10 integers from standard input, one by one and store them in an array of length 10. Compute the minimum, maximum and average value for the array. Display two lines: 1) The list of values in the array. Format: Values: x1, x2, ..., X10 2) A line containing the statistics. Format: Min: X, Max: X, Avg: X.XX Use two decimals for the average. Input Format: Read from standard input 10 integers, one at a time. Output Format: The following three lines: Type 10 integer values: Values: x1, x2, ..., X10 Min: X, Max: X, Avg: X.XX

Answer 1

CODE IN JAVA:

Hwk2.java file:

import java.util.Scanner;

public class Hwk2 {

public static void main(String[] args) {

//creating object to the Scanner class

Scanner sc = new Scanner(System.in);

//declaring array

int arr[] = new int[10];

//taking input from the user

System.out.println("Type 10 integer values:");

int sum=0,min=99999,max = -99999;

for(int i=0;i<10;i++) {

arr[i] = sc.nextInt();

sum += arr[i];

if(arr[i]<min)

min = arr[i];

if(arr[i]>max)

max = arr[i];

}

//calculating average

double avg = sum / 10.0;

System.out.print("Values: ");

for(int val :arr) {

System.out.print(" "+val+" ");

}

//displaying result

System.out.print("\nMin= "+min+",");

System.out.print(" Max= "+max+",");

System.out.printf(" Avg= %.2f,",avg);

System.out.println("");

}

}
