About Question enthuware.ocpjp.v21.2.4033 :

The given answer in the first option states that the output will be "10.0 10 10", but the correct output is "10.0 10 10.0".

This discrepancy occurs because the variable e is a double, not an int. Specifically, e is assigned the result of mean(d, d), which calls the method:

Code: Select all

double mean(int i, int j) { 
    return Math.sqrt(i * j); 
}

Since d = 10, the method computes:

Code: Select all

Math.sqrt(10 * 10) = 10.0;  // Returns a double
