Question

Which of the following is an invalid statement?

Options

• A class is a composite data type

• Statement import is used for including a package

• Primitives have fixed size

• String is a primitive

Answer 1

String is a primitive

Explanation:

This statement is invalid because String is a non-primitive (reference) data type in Java. Unlike primitive types (like int, char, or double) which hold raw values directly in fixed memory slots, a String is an object instantiated from a full class in the java.lang package designed to hold and manipulate character sequences.
