How may String Objects are created in java (By the following code)

Question

How many String objects are created in java by the following code: if there is no String object in the String pool containing the same value . (I read somewhere that Since we are passing arguments as "Hello", which is a String literal, it will also create another object as "Hello" on string pool. )

String s="Hello";

Answer 1

Only one object will be created in the string constant pool. Reason behind is while we creating the object,we didn't use any "new" keyword.

Answer 2

Only one String literal will be created in the String constant Pool.

Answer 3

No object is created but rather value is inserted in String pool if it is inserted before

Answer 4

One String Object (Literals are also Objects) is created IF "Hello" is NOT already present in the String pool.

Answer 5

You need to differentiate between literals which are loaded to the string pool when the class is loaded and passed around (this is your case) and the case of creating a string object by actually parsing/reading/constructing something.

The later case is of course much more often happening in programs, and it will always generate a new String object (even when the string value itself is already in the string pool).
