String vs StringBuffer == and .equals methods

	str1==str2	str1.equals(str2)
String	Compares Objs location	Compares Objs String contents
StringBuffer, StringBuilder	Compares Objs location	If and only if str1==str2 would be True.

 

So if we need to compare or sort in StringBuffer / StringBuilder we need to turn them into String first. For example:

if (str1.ToString() = str2.ToString())   {

System.out.println(“True”);

}   else   {

System.out.println(“False”);

}
