public static void main(String args[ ])

{

Scanner in=new Scanner(System.in);

int a,b,c,sum=0;

double avg=0.0;

sum=a+b+c;

avg=sum/3.0;

System.out.println("The sum of the three numbers="+sum);

System.out.println("The average of the three numbers="+avg);

}

{

public static void main(int a,int b,int c)

{

int sum=0;

double avg=0.0;

sum=a+b+c;

avg=sum/3.0;

System.out.println("The sum of the three numbers="+sum);

System.out.println("The average of the three numbers="+avg);

}
