In string concatenation what is the use of ""between two variables?

Question

When I wrote "My name is "+firstname+lastname It printed the same text as "My name is"+firstname+""+lastname would give. So what is the use of ""between firstname and lastname?

Answer 1

String firstname="Gaurav",lastname="Agrawal";
String str="my name is " + name +" "+ lastname;

//might is was " " , not ""
//" " is used to provide some space between firstname & lastname
//if we have not used " " , then str will be "GauravAgrawal"
//when we use " " , then str will be "Gaurav Agrawal"

//hope it helps ☺

Answer 2

yeah @LunarCoffee 😃

Answer 3

No difference as it's indicating an empty string was used. Otherwise it's most likely a space like this " " to separate words in between. 😉
