Varied amount of input data

Question

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non-negative integers as input, and outputs the max and average. A negative integer ends the input and is not included in the statistics. Assume the input contains at least one non-negative integer.

Output the average with two digits after the decimal point followed by a newline, which can be achieved as follows:

System.out.printf("%.2f\n", average);

Ex: When the input is:

15 20 0 3 -1

the output is:

20 9.50

Answer 1

class Solution{

public static int maximum(int[] data){

if (data.length == 0){

return 0;

}

int max_value = -10000000;

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

if(data[i] > max_value){

max_value = data[i];

}

}

return max_value;

}

public static double average(int[] data){

if (data.length == 0){

return 0.00;

}

double summation = 0;

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

summation += data[i];

}

return summation/data.length;

}

public static void main(String[] args){

int[] data = new int[args.length];

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

data[i] = Integer.parseInt(args[i]);

}

System.out.print(maximum(data) + " ");

System.out.printf("%.2f\n", average(data));

}

}
