Java help

[touch]

i have this code

int marker = 0;
for(int x = 0; x < arraylength; x++)
{
	if(name==players[x].getPlayerName() && surname == players[x].getPlayerSurname())
{
	marker = x;
}
}

this is how i set up my array:
Player[] players = new Player[arraylength];
but im getting a null pointer error when i run it
Anybody have any ideas?
