Question

Computer Network

Let the RRT’s be 40, 45, 56, 131, 87 and 68 for 6 ping requests to the same host. Write a program(Java) to calculate the minimum, maximum, mean, standard deviation of the given RRT which helps in finding the ping stats. Provide output as screenshot and include the program source code as well.

Answer 1

CODE:

public class RRT {

public static void main(String[] args) {

// TODO Auto-generated method stub

int a[]= {40, 45, 56, 131, 87, 68 };

int min=a[0],max=a[0],mean=0;

double standardDeviation=0.0;

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

{

if(min>a[i])

min=a[i];

}

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

{

if(max<a[i])

max=a[i];

}

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

{

mean=mean+a[i];

}

mean=mean/6;

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

standardDeviation += Math.pow(a[i] - mean, 2);

}

standardDeviation= Math.sqrt(standardDeviation/a.length);

  

System.out.println("Minimum of RRT is "+min);

System.out.println("Maximum of RRT is "+max);

System.out.println("Mean of RRT is "+mean);

System.out.println("Standard deviation of RRT is "+standardDeviation);

}

}

Output:
