How many data types does Java have for whole numbers?

In Java, there are indeed four primary data types specifically designed for representing whole numbers, which are commonly referred to as integer types. These types are:

1. byte: This data type is an 8-bit signed integer. It can hold values from -128 to 127. It is useful for saving memory in large arrays when you know that the values will be mostly small.

2. short: This is a 16-bit signed integer with a range of -32,768 to 32,767. It also helps conserve memory in larger arrays of integer values.

3. int: This is a 32-bit signed integer, which is the most commonly used integer type in Java. It can hold values from -2,147,483,648 to 2,147,483,647.

4. long: This is a 64-bit signed integer, capable of holding larger values ranging from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. It is used when a wider range than int is required.

These four types cover the basic requirements for whole number representation in Java, indicating that the correct count
