{

Scanner sc= new Scanner(System.in);

System.out.print("Enter the first number: ");

double num1=sc.nextDouble();

System.out.print("Enter the second number: ");

double num2=sc.nextDouble();

System.out.print("Enter the third number: ");

double num3=sc.nextDouble();

double sum= num1+num2+num3;

double avg=sum/3;

System.out.println("The sum of the 3 numbers is: "+sum) ;

System.out.println("The average of the 3 numbers is: "+avg) ;

System.out.println("Enter 3 numbers..");

a=sc.nextDouble();

b=sc.nextDouble();

c=sc.nextDouble();

s=a+b+c;

av=s/3.0;

System.out.println("Sum is: "+s);

System.out.println("Average is: "+av);

}
