Java Utililty Methods Array Contain

boolean ARRAY_Contains(int value, int[] array)
returns true if the array contains the value, or false if it does not

for (int x = 0; x < array.length; x++) {
 if (array[x] == value)
 return true;
return false;

boolean arrayContains(byte[] a, int offset, byte[] b)
Returns true if an array's elements appear inside another array.

if (a.length < offset + b.length)
 return false;
for (int i = 0; i < b.length; i++) {
 if (a[offset + i] != b[i])
 return false;
return true;

boolean arrayContains(char[] chars, char cToFind)
array Contains

for (char c : chars) {
 if (c == cToFind) {
 return true;
return false;

boolean arrayContains(char[] chars, char cToFind)
array Contains

for (char c : chars) {
 if (c == cToFind) {
 return true;
return false;

boolean arrayContains(final byte[] what, final byte[] b)
array Contains

boolean r = false;
for (int i = b.length - 1; i > what.length; i--) {
 int j = what.length;
 while (j > -1) {
 if (b[i] != what[j]) {
 r = false;
 continue;
 } else {
...

boolean arrayContains(final E[] arr, final E targetValue)
Check if an array contains a value, very efficient

for (final E s : arr) {
 if (s.equals(targetValue))
 return true;
return false;

boolean arrayContains(final int[] array, final int v)
Determines if a value exists in an array.

for (int i : array)
 if (i == v)
 return true;
return false;

boolean arrayContains(final Object[] a, final Object v)
array Contains

for (final Object x : a) {
 if (v == null) {
 if (x == null)
 return true;
 } else {
 if (v.equals(x))
 return true;
return false;

boolean arrayContains(final String[] array, String needle)
Returns true if the String array contains a string.

needle = nn(needle);
for (final String element : array) {
 if (needle.equalsIgnoreCase(element.trim())) {
 return true;
return false;

boolean arrayContains(final T[] array, final T v)
array Contains

for (final T e : array)
 if (e == v || v.equals(e))
 return true;
return false;
