❮ Previous Next ❯ Apex Control Statements Control statements are used to make decisions in your Apex programs. Based on certain conditions, they decide which block of code should be executed.    In Apex, the two main types of decision-making control statements are:  • if, if-else, if-else if – for conditional logic • switch –

❮ Previous Next ❯ Apex Operators Operators are special symbols used to perform operations on variables and values. These operations can be mathematical, logical, comparative, or assignment based. In Apex, just like in other programming languages, operators help us manipulate data, make decisions, and control program flow.  Let’s break them down into different categories: 1.

They help you represent characters that can’t be typed directly, like tabs (a blank space), newline, or quotes (“). In Apex, escape sequences are also
