edit: String in java is not primitive type.

Answer 2

From my understanding string, char, int, float, double, and boolean are primitive types in Java that do not require explicit instiantiation.

Answer 3

as you can see
a b are same object in memory,
but c not

String a = "Hello";
String b = "Hello";
String c = new String("Hello");

System.out.println(
System.identityHashCode( a) +"\n"+
System.identityHashCode( b) +"\n"+
System.identityHashCode( c)
);

also String is Object and all public objects can be created by new keywords
