String is Immutable - String Vs String builder

String is Immutable - String Vs String builder

String is immutable

  • String a=”a”; address is 12345
  • a=”b”; address will be 3456
  • String a=new String(“a”);
  • Will create one object in String pool and create one more object for new operator will get created and that will point to it.
  • String a=”a”; will create object in string pool and object a will point to it.

StringBuffer is mutable

  •  StringBuffer b=”a”; address is 12345
  •  b=”b”; address is 12345
  •  This is synchronized

StringBuilder : This is similar to StringBuffer but this is not synchronized

Who ever writes Inappropriate/Vulgar comments to context, generally want to be anonymous …So I hope U r not the one like that?
For lazy logs u can at least use Name/URL option which don’t even require any sign-in, good thing is that it can accept your lovely nick name also and URL is not mandatory too.
Thanks for your patience
