class test1
{
static public void main(String args[])
{
String sb1 = new String("Amit");
String sb2= new String("Amit");
String ss1 = "Amit";
System.out.println(sb1==sb2);//false,
System.out.println(sb1.equals(sb2));//true
System.out.println(sb1.equals(ss1));//true
}
}

class test1
{
static public void main(String args[])
{
StringBuffer sb1 = new StringBuffer("Amit");
StringBuffer sb2= new StringBuffer("Amit");
String ss1 = "Amit";
System.out.println(sb1==sb2);//false
System.out.println(sb1.equals(sb2));//false
System.out.println(sb1.equals(ss1));//false
}
}
Is the output as expected in case of string buffer??

If you check the API, you'll see that StringBuffer does not override the equals method, so it invokes the method as defined in Object (which is basically ==).
 
It is sorta covered in the JavaRanch Style Guide.
