Intro to Variables

Intro to Variables

Variables are used to store information that can be referenced and manipulated in a program. In Apex, you declare a variable by specifying its data type and a name.

Example

// Declare a variable of type String
String myName;

// Assign a value to the variable
myName = 'John Doe';

// Declare and initialize a variable in one line
Integer myAge = 30;
