Java Utililty Methods Array Append

int addToArray(final int[] array, int index, final String csvString, final String delim)
add To Array

final StringTokenizer tokenizer = new StringTokenizer(csvString, delim);
while (tokenizer.hasMoreTokens()) {
 array[index++] = Integer.parseInt(tokenizer.nextToken());
return index;

int[] addToArray(int[] a, int value)
add To Array

if (a == null || a.length == 0) {
 return new int[] { value };
int[] array = Arrays.copyOf(a, a.length + 1);
array[a.length] = value;
return array;

String[] addToArray(String[] items, String str)
Adds a string to a string array.

List<String> itemList;
if (items == null) {
 itemList = new ArrayList<String>();
} else {
 itemList = new ArrayList<String>(Arrays.asList(items));
if (str != null) {
 itemList.add(str);

byte[] appendArray(final byte[] buffer1, final byte[] buffer2)
Appends the second array to the first array.

final byte[] newBuffer = new byte[buffer1.length + buffer2.length];
int pos = 0;
System.arraycopy(buffer1, 0, newBuffer, pos, buffer1.length);
pos += buffer1.length;
System.arraycopy(buffer2, 0, newBuffer, pos, buffer2.length);
return newBuffer;

int[][] appendArray(int[][] array, int[] staple)
append Array

int[][] output = new int[array.length + 1][];
System.arraycopy(array, 0, output, 0, array.length);
output[array.length] = staple;
return output;

Object[] appendArray(Object[] arr, Object obj)
Append an Object at end of array

Object[] newArr = new Object[arr.length + 1];
System.arraycopy(arr, 0, newArr, 0, arr.length);
newArr[arr.length] = obj;
return newArr;

Object[] appendArray(Object[] array1, Object[] array2)
Appends array2 to the end of array1 and returns the result

Object[] result = new Object[array1.length + array2.length];
System.arraycopy(array1, 0, result, 0, array1.length);
System.arraycopy(array2, 0, result, array1.length, array2.length);
return result;

String[] appendArray(String[] A, String... B)
Appends String(s) B to array A.

return concatArrays(A, B);

void appendArray(StringBuilder bld, Object[] array, String sep)
Appends an array to a string builder using the specified separator string.

String curSep = "";
for (Object obj : array) {
 bld.append(curSep);
 bld.append(obj);
 curSep = sep;

StringBuilder appendArray(StringBuilder sb, int[] arr)
append Array

for (int i : arr) {
 sb.append(i);
 sb.append(System.getProperty("line.separator"));
return sb;
