Question

Write a program in Java to find average & median of 3 numbers.

Answer 1

This isn't a question. You haven't even attempted to do this....However, I will write the idea program to do so. In the future, you need to attempt this first and show your progress.

Answer 2

//imports go here
//You'd want to input arrays and the use of the System.out."method". I don't remember
//Them off the top of my head.

public class Example
{
public static void main(String args[])
{
int threeNum[] = {5, 1, 2};
System.out.println("The median of threeNum is: " + median(threeNum) + ".";
System.out.println("The average of threeNum is: " + average(threeNum) + ".";
}

private double median(int threeNum[])
{
int sorted[] = Arrays.sort(threeNum); //assuming the 3 numbers
return sorted[2];
//Again, I would never use this because this is just 3 number example
}

private double average(int threeNum[])
{
double sum = 0;
for(int i = 0; i < threeNum.length; ++i)
sum += threeNum[i];

return ((double)sum / i);
}
