In case of �==�object reference are compared. Hence it returns false since sb1 and sb2 are in two different location. Since equals method is not overridden in StringBuffer class. Default implementation from Object class is present in StringBuffer. The default implemation is again check for object reference, not the object value. Hence since sb1 and sb2 are referring different memory location in the second case also it is returns false.
