java: array if all the same

Question

I have a array:

int tarningar[] = new int[5];

That holds numbers. When all the numbers are the same, system.out.println('ok');

How can I do this?

Answer 1

Here's a more succinct Java 8 streams example:

Arrays.stream(tarningar).distinct().count() == 1

Answer 2

boolean flag = true;
int first = tarningar[0];
for(int i = 1; i < 5 && flag; i++)
{
  if (tarningar[i] != first) flag = false;
}
if (flag) System.out.println("ok");
