Method

doublefindMax(List nums)
find Max 
double m = Double.MIN_VALUE;
for (Double x : nums) {
    if (m < x)
        m = x;
return m;
doublefindMax(List values)
find Max 
double max = Double.MIN_VALUE;
for (Double d : values) {
    if (d > max)
        max = d;
return max;
intfindMaxDeformationCount(final List counts)
find Max Deformation Count 
double max = 0;
for (int[] iA : counts) {
    max = Math.max(max, iA[iA.length - 1]);
return (int) max;
MapfindMaximalMatch(List> mapList, LinkedHashMap fieldsByPriority)
For a list of Map find the entry that best matches the fieldsByPriority Ordered Map; null field values in a Map in mapList match against any value but do not contribute to maximal match score, otherwise value for each field in fieldsByPriority must match for it to be a candidate. 
int numFields = fieldsByPriority.size();
String[] fieldNames = new String[numFields];
Object[] fieldValues = new Object[numFields];
int index = 0;
for (Map.Entry<String, Object> entry : fieldsByPriority.entrySet()) {
    fieldNames[index] = entry.getKey();
    fieldValues[index] = entry.getValue();
    index++;

longgetMax(List numList)
get Max 
long max = Long.MIN_VALUE;
if (numList != null) {
    for (Iterator i = numList.iterator(); i.hasNext();) {
        max = Math.max(((Long) i.next()).longValue(), max);
} else {
    max = -1;
return max;
DoublegetMax(List aList)
get Max 
Iterator<Double> itr = aList.iterator();
if (aList.size() > 0) {
    Double max = aList.get(0);
    while (itr.hasNext()) {
        Double d = itr.next();
        if (d > max) {
            max = d;
    return max;
return null;
doublegetMax(List d)
Returns the maximum value of an Arraylist with doubles 
double res = -Double.MAX_VALUE;
for (Double db : d) {
    if (db > res)
        res = db;
return res;
doublegetMax(List list)
get Max 
double max = -Double.MAX_VALUE;
for (double d : list) {
    if (d > max)
        max = d;
return max;
doublegetMax(List numbers)
Finds the maximum from a list of Doubles.

If the list is empty, 0 is returned. 

if (numbers.size() == 0) {
    return 0.0;
double max = numbers.get(0);
for (Double number : numbers) {
    max = Math.max(max, number);
return max;
...
IntegergetMax(List list)
get Max 
if (list == null) {
    throw new IllegalArgumentException("Empty list not allowed");
Integer max = Integer.MAX_VALUE;
for (Integer number : list) {
    max = Math.max(number, max);
return max;
