What are the different data types in Java with examples?

What are the different data types in Java?

Java has two main categories of data types: primitive and reference types. Primitive types include int, char, double, etc.

Can you give me examples of each primitive data type?

Sure! For example, an int can be 42, a char can be 'A', and a double can be 3.14.

What about reference data types?

Reference types include classes, arrays, and interfaces. For instance, a String is a reference type, like String name = "John";.

How do I choose which data type to use?

Choose based on the kind of data you need to store. Use primitives for simple values and reference types for complex objects.
