Method Detail

mergeArrays

public static <T> T[] mergeArrays(T[] firstArray,
                  T[] secondArray)

Merges two arrays in a third array.

Type Parameters:

T -

Parameters:

firstArray -

secondArray -

Returns:

mergeArrays

public static int[] mergeArrays(int[] firstArray,
                int[] secondArray)

addToArray

public static <T> T[] addToArray(T[] array,
                 T element)

addToArray

public static int[] addToArray(int[] array,
               int element)

subArray

public static <T> T[] subArray(T[] src,
               int from,
               int to)

subArray

public static int[] subArray(int[] src,
             int from,
             int to)

asList

public static <T> List<T> asList(T... array)

Returns the List that contains elements from array. NOTE: vararg of parameterized types (here @param array) for primitive arrays doesn't work properly. This utility have to be accomplished with asList methods for each primitive arrays!!!

Type Parameters:

T -

Parameters:

array -

Returns:

asList

public static List<Integer> asList(int[] array)

asList

public static List<Long> asList(long[] array)

asList

public static List<Float> asList(float[] array)

asArray

public static int[] asArray(List<Integer> integerList)

toIntArray

public static int[] toIntArray(Integer... integerArray)

toIntegerArray

public static Integer[] toIntegerArray(int... intArray)

parseStringListAsInt

public static int[] parseStringListAsInt(List<String> stringList)

parseStringArray

public static int[] parseStringArray(String[] stringArray)

toStringList

@Deprecated
public static List<String> toStringList(List<?> list)

Deprecated.

Converts an Objects list to the list of Strings by calling toString method of each Object from incoming list.

Parameters:

list - incoming list of Objects

Returns:

list where each incoming object converted to string.

toStringList

public static List<String> toStringList(int... array)

toStringList

public static <T> List<String> toStringList(T... array)

toString

public static <T> String toString(int... array)

toString

public static <T> String toString(T... array)

contains

public static boolean contains(int[] array,
               int element)

contains

public static <T> boolean contains(T[] array,
                   T element)

intersection

public static int[] intersection(int[] array1,
                 int[] array2)

Finds all elements that the array1 and the array2 have in common. The array1 and the array2 must be sorted ascent.

Parameters:

array1 -

array2 -

Returns:

the array of elements that the array1 and the array2 have in common

isSorted

public static boolean isSorted(boolean desc,
               int... array)

isSorted

public static boolean isSorted(int... array)

createInstance

public static <T> T[] createInstance(T[] a,
                     int size)

main

public static final void main(String[] args)
