Java Utililty Methods SortedSet Usage

String concatStringList(SortedSet sortedDependencies)
Concatenates a SortedSet of Strings with a semicolon between them.

String concatenatedString = "";
for (String s : sortedDependencies) {
 concatenatedString = concatenatedString.concat(s + ";");
return concatenatedString;

T findLT(SortedSet ss, T x)
Finds the largest value that is smaller than x in a SortedSet

SortedSet<T> p = ss.headSet(x);
return p.isEmpty() ? null : p.last();

int findPositionFor(final T item, final SortedSet values)
find Position For

final SortedSet<T> head = values.headSet(item);
return head.size();

T firstOrNull(SortedSet set)
first Or Null

if (set == null || set.isEmpty()) {
 return null;
return set.first();

int nextValue(SortedSet valueSet, int startValue)
next Value

if (valueSet == null) {
 return startValue;
if (valueSet.contains(startValue)) {
 return startValue;
SortedSet<Integer> tailSet = valueSet.tailSet(startValue + 1);
if (tailSet.isEmpty()) {
...

boolean sortedSetIsAssignableFrom(Class aClass)
Determines if the SortedSet interface is either the same as, or is a superinterface of, the class or interface represented by the specified Class parameter.

return SortedSet.class.isAssignableFrom(aClass);

SortedSet sortedSetOf(final Object obj, final Class castTo)
sorted Set Of

return (SortedSet<T>) obj;

double[] toDoubleArray(final int[] intArray)
to Double Array

final int length = intArray.length;
final double[] doubleArray = new double[length];
for (int i = 0; i < intArray.length; i++) {
 doubleArray[i] = intArray[i];
return doubleArray;
