Can you help? I tried to output max, min and average variables of massive

Question

package com.company;

public class Main {

public void main (String[] args){
int l = 100;
double [] massive = new double [l];
double minimum = 0;
double maximum = 0;
double summary = 0;
for (int i = 0; i < l; i++) {
massive [i] = Math.random();
if (massive[i] < minimum) {
minimum = massive[i];
}
if (massive[i] > minimum) {
maximum = massive[i];
}
summary = summary + massive[i];

}
double average = summary/l;

System.out.println(maximum);
System.out.println(minimum);
System.out.println(average);
}
}
It outputs to console
java.lang.NullPointerException: null receiver
What I did wrong? I tried to google this, but I don't know where null there.

No exception working fine. You just missed to make void method static
