when we create a String variable as
String str="pawan";
Stirng str=new Sring("pawan");
what is difference between both .

[Pawan Sinha]

string str= new String("Pawan") creates a new memory space for string str, so if u will equate the two string variables declared as in yr query, the result will be false as these two string variable are having diffrent reference.

This is not a servlet question, so I've moved it to "Java in General, Beginner"

This thread has an excellant explaination of the difference between the literal and the object.

String str = "pawn"
stores the constant pawn in the variable str
String str = new String(pawn)
creates a new string object and stores the refernce to that object in str and pawn is passed to the constructor of that object
