Method

booleanallEqual(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;
booleanallEqual(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;
booleanallEquals(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;
booleanallEquals(final String value, final String... strings)
Return true if all strings are the same.
