Question

Write a Java program to get the difference between the largest and smallest values in a user inputed array of integers. The length of the array must be 1 and above

Answer 1

Solution.

import java.util.Scanner;

classMin_max_array

{

//Steps to get maximum number from array elements

int getMax(int[]inputArray)

{

int maxValue=inputArray[0];

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

{

if(inputArray[i]>maxValue)

{

maxValue=inputArray[i];

}

}

return maxValue;

}

//Steps to get minimum number from array elements

int getMin(int[]inputArray)

{

int minValue=inputArray[0];

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

{

if(inputArray[i]<minValue)

{

minValue=inputArray[i];

}

}

return minValue;

}

}

public class Array_difference

{

public static void main(String[] args)

{

int n;

// creating object of scanner.

Scanner sc = new Scanner(System.in);

//Enter number of array elements here.

System.out.print("Enter number of elements you wants to enter : " );

//Read the entered number and store it in variable "n".

n=sc.nextInt();

int arr[]=new int[n];

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

{

System.out.print("Enter ["+(i+1)+"] element : " );

arr[i]=sc.nextInt();

}

MinMaxInArray mm=new MinMaxInArray();

//Print maximum, minimum, difference of array elements.

System.out.println("Maximum value is : " +mm.getMax(arr));

System.out.println("Minimum value is : " +mm.getMin(arr));

int Difference=mm.getMax(arr)-mm.getMin(arr);

System.out.print("Difference between Minnimum and Maximum in array is : " +Difference );

}

}

Output

Enter number of elements you wants to enter :10

Enter [1] element : 25

Enter [2] element : 36

Enter [3] element : 74

Enter [4] element : 85

Enter [5] element : 964

Enter [6] element : 215

Enter [7] element : 36

Enter [8] element : 58

Enter [9] element : 98

Enter [10] element : 123

Maximum value is : 964

Minimum value is : 25

Difference between Minnimum and Maximum in array is : 939
