3. Apex Methods:

  • Methods are defined within classes using the “void” keyword (for methods that don’t return a value) or specifying the return type.
  • Methods can have parameters and may be static or instance methods.

4. Apex Variables:

  • Variables are declared using the syntax: datatype variableName [= value];
  • Apex supports primitive data types (such as Integer, String, Boolean), collections (Lists, Sets, Maps), and custom objects.

5. Apex Control Flow Statements:

  • Apex supports common control flow statements like if-else, switch, for loop, while loop, and do-while loop.
  • Conditional expressions are enclosed within parentheses, and blocks of code are enclosed within curly braces.
