Given:

public class Thing {
	private String name;
	public Thing(String name) {
 		this.name = name;
	}
	public String toString() {
 		return name;
	}
}

and

public class Tester {
	public static void main(String[] args) {
 		Thing[] things = processThings();
 		/* line 1 */
 		for (Thing t : things) {
  			System.out.println(t);
 		}
	}
	public static Thing[] processThings() {
 		Thing[] things = new Thing[3];
 		things[0] = new Thing("Hat");
 		things[1] = new Thing("Rat");
 		things[2] = things[0];
 		things[0] = new Thing("Cat");
 		things[1] = things[2];
 		return things;
	}
}
