Answer 2

Answer:

This is the required Java program for the question.

import java.util.*;

public class MinMax {

   public static void main() {

       int a[]=new int[4];

       a[0]=Integer.MIN_VALUE;

       a[1]=Integer.MAX_VALUE;

       Scanner sc=new Scanner(System.in);

       System.out.println("Enter 5 numbers...");

       for(a[3]=0;a[3]<5;a[3]++)  {

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

           a[2]=sc.nextInt();

           a[0]=Math.max(a[0],a[2]);

           a[1]=Math.min(a[1],a[2]);

       }

       System.out.println("Largest Number: "+a[0]);

       System.out.println("Smallest Number: "+a[1]);

       sc.close();

   }

}

Another Approach:

import java.util.*;

public class Max {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

int a[]=new int[5];

System.out.println("Enter 5 numbers..");

a[0]=sc.nextInt();

a[1]=sc.nextInt();

a[2]=sc.nextInt();

a[3]=sc.nextInt();

a[4]=sc.nextInt();

System.out.println("Largest Number: "+Math.max(a[0],Math.max(a[1],Math.max(a[2],Math.max(a[3],a[4])))));

sc.close();

}

}

Explanation:

• The Integer.MIN_VALUE stores the lowest value in the integer range whereas the Integer.MAX_VALUE stores the highest value in the integer range.
• An array named a[] is declared in which, a[0] (number at first index) stores the highest number among 5 numbers. We assume that Integer.MIN_VALUE is the highest number.
• Similarly, a[0} stores the lowest number among the 5 numbers. We assume that Integer.MAX_VALUE is the lowest number.
• Now, we will iterate a loop 5 times. Inside the loop, we will ask the user to enter a number. The entered number will be stored at index 2.
• Now, using Math.max() and Math.min() function, we will compare the number entered with the maximum and minimum values. So, at last, the maximum and minimum value will be stored at index 0 and 1 respectively.
• At last, their values will be displayed on the screen.

Restrictions Followed:

• Not to use any conditional construct. ✔
• Not to use more than 2 variables. ✔ (Used only 1 variable - a[], array is considered as 1 variable only)
