The list of methods to do Array Equal are organized into topic(s).

Method

boolean allEqual(int[] arr)
Returns true if all values in the array are equal.

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

boolean allEqual(int[] values)
Checks if elements in the given array are all equal.

if (values.length == 0) {
 return true;
int value = values[0];
for (int i = 1; i < values.length; i++) {
 if (values[i] != value) {
 return false;
return true;

boolean allEquals(double[][] sims)
all Equals

double prev = 0;
for (int i = 0; i < sims.length; i++) {
 for (int j = 0; j < sims[0].length; j++) {
 if (!(i == 0 && j == 0))
 if (sims[i][j] != prev)
 return false;
 prev = sims[i][j];
return true;

boolean allEquals(final String value, final String... strings)
Return true if all strings are the same.

for (final String s : strings) {
 if (s == null && value != null || s != null && value != null && !s.equals(value)) {
 return false;
return true;
