Question

Write a program to input 3 nos (positive/negative). If they are unequal display the greatest. Or else display they are equal. Also display whether the nos are all positive or all negative or mixed

Answer 1

Answer:

import java.util.Scanner;

public class Demo {

  public static void main(String args[]) {

      Scanner sc=new Scanner(System.in);

      System.out.println("Enter first number : ");

      int a=sc.nextInt();

      System.out.println("Enter second number : ");

      int b=sc.nextInt();

      System.out.println("Enter third number : ");

      int c=sc.nextInt();

      if(a==b&&b==c)

      System.out.println("All are equal");

      else if(a>=b&&a>=c)

      System.out.println("Largest number is "+a);

      else if(b>=a&&b>=c)

      System.out.println("Largest number is "+b);

      else if(c>=a&&c>=b)

      System.out.println("Largest number is "+c);

      if(a>=0&&b>=0&&c>=0)

      System.out.println("All are positive numbers");

      else if(a<=0&&b<=0&&c<=0)

      System.out.println("All are negative numbers");

      else

      System.out.println("These are mixed(positive & negative)");

  }

}

Answer:

import java.util.Scanner;

public class Demo {

public static void main(String args[]) {

Scanner sc=new Scanner(System.in);

System.out.println("Enter first number : ");

int a=sc.nextInt();

System.out.println("Enter second number : ");

int b=sc.nextInt();

System.out.println("Enter third number : ");

int c=sc.nextInt();

if(a==b&&b==c)

System.out.println("All are equal");

else if(a>=b&&a>=c)

System.out.println("Largest number is "+a);

else if(b>=a&&b>=c)

System.out.println("Largest number is "+b);

else if(c>=a&&c>=b)

System.out.println("Largest number is "+c);

if(a>=0&&b>=0&&c>=0)

System.out.println("All are positive numbers");

else if(a<=0&&b<=0&&c<=0)

System.out.println("All are negative numbers");

else

System.out.println("These are mixed(positive & negative)");

}
