Why new keyword not needed for String

Question

I am new in java.

In java, String is a class.But we do not have to use new keyword to create an object of class String<

Answer 1

In java
"==" compares the left & right hand sides memory locations(and not the value at that memory location) and therefore in case of

new String("hai")==new String("hai")

it returns false.

In case of "Hai"=="Hai", java doesn't allocate separate memory for same string literal therefore here "==" returns true. You can always use equals method to compare values.
