What is the cleanest and most efficient way of determining the number of boolean values set to 1 in an array of objects?

I have an array of objects that have a boolean value which determines whether the object (a node) should be displayed to the screen.  I want to determine the total number of objects that should be displayed. In other words, all the objects with the boolean variable 'display' equal to 1.

1. int total;
2. 
   
3. for (int i = 0; i < node.length; i++) {
4.   if (node[i].display.equals(1)) {
5.     total++;  
6.   }
7. }

Can this be done in one line with an array function rather than using a loop?
