In Apex, Integer is a primitive data type used to represent whole numbers. It is a 32-bit signed integer, allowing values from -2,147,483,648 to 2,147,483,647. Developers use the Integer data type when working with variables that store whole numbers, such as counts, indices, or quantities in Salesforce Apex code.

Here's an example of declaring and initializing an integer variable:

Integer myNumber = 42;

In this example, myNumber is a variable of type Integer, and it is assigned the value 42. Developers commonly use integers for arithmetic operations, loop counters, and other scenarios where whole numbers are appropriate.
