Java string intern and literal

Question

Are the below two pieces of code the same?

String foo = \"foo\";
String foo = new String(\"foo\").intern();

Answer 1

The first one i.e.

    String foo = "foo";

in this line, we are creating a String using String literals. That means the string is automatically saved in String Constant pool.

In the 2nd one , i.e. -

    String foo = new String("foo").intern();

Here we are creating a String using new String() & then manually saving it to the String constant pool. If we didn't have mentiones intern() , it would not have saved in the String constant pool.
