for (int i = 0; i < array.length; i++) {
    newArray[i] = array[i];
return newArray;
double[]toPrimitive(Double[] doubles)
to Primitive 
double[] dArray = new double[doubles.length];
int i = 0;
for (double d : doubles) {
    dArray[i++] = d;
return dArray;
double[]toPrimitive(Double[] vals)
to Primitive 
double[] v = new double[vals.length];
for (int i = 0; i < v.length; i++) {
    v[i] = vals[i];
return v;
booleantoPrimitive(final Boolean b)
to Primitive 
return b == null ? false : b.booleanValue();
chartoPrimitive(final Character value, final char defaultValue)
