Just try this sample and click in the preview (1x import, 4x loop branches). Its difficult to explain but you see easily it is not ok. Especially the last branch for the inner loop of the second nested loop is strange.

import java.util.Arrays;
import java.util.Collection;
import java.util.Iterator;

public class A {
	public A() {
		Collection<Collection<String>> cc = Arrays.asList(Arrays.asList(""));
		for (final Iterator<Collection<String>> outer = cc.iterator(); outer.hasNext();) {
			final Collection<String> c = outer.next();
			for (final Iterator<String> inner = c.iterator(); inner.hasNext();) {
				System.out.println(inner.next());
			}
		}
	}

	void foo() {
		int[][] box = { { 1, 2 }, { 3, 4 } };
		for (int i = 0; i < box.length; i++) {
			int[] line = box[i];
			for (int j = 0; j < line.length; j++) {
				System.out.print(line[j]);
			}
		}
	}
}
