Finding the max/min value in an array of primitives using Java

Question

It\'s trivial to write a function to determine the min/max value in an array, such as:

/**
 * 
 * @param chars
 * @return the max value in the array of chars         


        

Answer 1

Here is a solution to get the max value in about 99% of runs (change the 0.01 to get a better result):

public static double getMax(double[] vals){
    final double[] max = {Double.NEGATIVE_INFINITY};

    IntStream.of(new Random().ints((int) Math.ceil(Math.log(0.01) / Math.log(1.0 - (1.0/vals.length))),0,vals.length).toArray())
            .forEach(r -> max[0] = (max[0] < vals[r])? vals[r]: max[0]);

    return max[0];
}
