  You are using the mutable StringBuilder objects as though they are immutable. This is more accurate: StringBuilder String1 = new StringBuilder("beautiful"); StringBuilder String2 = new StringBuilder(); //String1=beautiful //String2= String2 = String1.Append(" Picture"); //String1=beautiful Picture //String2=beautiful Picture String2 = String1.Remove(2, 4); //String1=beful Picture //String2=beful Picture String2 = String1.Insert(2, "auti"); //String1=beautiful Picture //String2=beautiful Picture String2 = String1.Replace("beautiful", "Wonderful"); //String1=Wonderful Picture //String2=Wonderful Picture

    In your example, you use the Stringbuilder object as though it is immutable: String2 = String1.Append(" Picture"); What you have done here, was to append " Picture" to String1, and then just changed the String2 reference to point to String1. You don't need to have 2 instances of the StringBuilder. Rather just create one, and treat it like the mutable object it is... Better Example: StringBuilder String1 = new StringBuilder("beautiful"); String1.Append(" Picture"); //String1="beautiful Picture" String1.Remove(2, 4); //String1="beful Picture" String1.Insert(2, "auti"); //String1="beautiful Picture" String1.Replace("beautiful", "Wonderful"); //String1="Wonderful Picture"
