That's because he's making references to an object and variables that don't exist; should be:
Code
public static void main (String[] args) {
Object tempObj = new Object();
Object obj1 = new Object();
Object obj2 = new Object();
obj1 = obj2;
obj2 = tempObj;
System.out.println("Objects switched");
}
class Object {
public void Object() {
...code here
}

The Object class already exists (java.lang.Object), so you don't need another class for it.
But OP, you provided the correct solution yourself.
