In Java, Why String is non-primitive data type?

Question

In Java, we can directly use String to declare a string variable name and specify its value. We do not have to define the string as an array by using new keywor

Answer 1

String is non-primitive because only class can have methods. Primitive can not. And String need many functions to be called upon while processing like substring, indexof, equals, touppercase. It would not have been possible without making it class.

Also class has made it possible to make strings immutable and final to enhance security and efficiency by allowing pooling.
