Equality of String objects

[Bryan Timmins]

Why is my brain melting on "equals()" vs. "=="?
The following prints out:

false
false
true
false

But I don't understand what makes
the StringBuffer objects behave differently. TIA

public class Equality
{
  public static void main (String args[])
  {
    StringBuffer strbuf = new StringBuffer("StringBuffer");
    StringBuffer strbuf1 = new StringBuffer("StringBuffer");
    System.out.println(strbuf.equals(strbuf1));
    System.out.println(strbuf == strbuf1);
    String a = new String("String");
    String b = new String("String");
    System.out.println(a.equals(b));
    System.out.println(a==b);
  }
}

Thanks Pho Tek,
That link sums it up. I did just discover my answer on another group. I also discovered that String overrides hashCode() to return based on the contents of the String rather than the unique values normally associated with Object's hashCode().
