?What is the difference between primitive and reference data types in Java

Primitive data types in Java represent basic values like integers, floating-point numbers, characters, and booleans, and they store the actual value. Reference data types, on the other hand, store references to objects in memory, allowing complex data structures and dynamic memory allocation.

?How can you convert one data type to another in Java

In Java, you can convert one data type to another using type casting. For primitive data types, you can perform explicit casting by placing the desired data type in parentheses before the value to be casted. For reference data types, you can use methods like toString() for converting to strings, or explicit casting for other conversions. Additionally, autoboxing and unboxing allow automatic conversion between primitive and wrapper classes.
