 int n=kb.nextInt();
        double massiv[]=new double[n];
        for(int i=0;i<=massiv.length;i++){
            massiv[i]=kb.nextDouble();
        }
        for(int i=0;i<=massiv.length;i++){
            gr=massiv[i]*gr;
            dr=massiv[i]+dr;
        }
        Re=gr/dr;
        System.out.println(+Re);

Indexes in an array go from 0 to n-1 where n is the length of the array ... you are also accessing the nth index by using <= in your for loops ... so if you change it to — mettleap, Nov 23 '18 at 22:12

Arrays are 0-indexed. An array of size 2 has 2 indexes: 0 and 1. Your loops are trying to access index 2 (since they're using <=), which doesn't exist.

Replace <= in your for-loops with <
