On Homework exercise for Java Collections Framework. The instruction
says to "... Add the following objects with properly initialized
values to the newly created HashSet object ... 2 String objects ... 3
Integer objects ... "
My questions is do I have to declare the String and Integer this way:
hs.add(new String("string1"));
hs.add(new Integer(7));
or can I just do it this way:
hs.add("string1");
hs.add(7);
