What are primitive data types in Apex?

Salesforce Apex Primitive datatypes are, Blob, Boolean, Date, DateTime, Decimal, Double, ID, Integer, Long, Object, String and Time. Reading this article, you can learn and test the Apex primitive datatypes in SalesForce.

What is the difference between primitive and complex data types?

The primitive data types are types like string , integer , boolean , etc. that can take a single value. The complex types consist of multiple values grouped together.

Is complex a primitive data type?

Complex types are nested data structures composed of primitive data types. These data structures can also be composed of other complex types. Some examples of complex types include struct(row), array/list, map and union. Complex types are supported by most programming languages including Python, C++ and Java.

What are the 5 primitive data types?

Primitive types are the most basic data types available within the Java language. There are 8: boolean , byte , char , short , int , long , float and double . These types serve as the building blocks of data manipulation in Java. Such types serve only one purpose — containing pure, simple values of a kind.

What is the incorrect primitive data type?

What is the incorrect statement about primitive data types? Primitive data types can not be directly used in any program. They are collectively of 8 types. These are used to create user defined datatypes such as objects which are not defined in language but are created by programmer.

What are built in Apex types?

Apex – Data Types

• Primitive (Integer, Double, Long, Date, Datetime, String, ID, or Boolean)
• Collections (Lists, Sets and Maps) (To be covered in Chapter 6)
• sObject.
• Enums.
• Classes, Objects and Interfaces (To be covered in Chapter 11, 12 and 13)

What are the 6 primitive data types?

There are 7 primitive data types: string, number, bigint, boolean, undefined, symbol, and null. Most of the time, a primitive value is represented directly at the lowest level of the language implementation. All primitives are immutable, i.e., they cannot be altered.

Can a class variable be an object in apex?

Object. We can refer this as any data type which is supported in Apex. For example, Class variable can be object of that class, and the sObject generic type is also an object and similarly specific object type like Account is also an Object.

What’s the difference between a primitive and a complex object?

A primitive is an indivisible, immutable object, while a complex object contains other objects, both primitives and complex objects. Object itself is considered a primitive because you can’t access the individual attributes of a complex object without casting first.
