If you know Java or Dotnet applications, then you may observe that everything is written as a class. There are different access levels. You can also define class within a class just like inner class and outer class etc.
Salesforce also provides similar syntax that is followed in Java. Syntax can be to defining a class or variables in class or a wrapper class everything is similar to the syntax followed in Java programming.
Let us see a class and things that can be done in a class in Salesforce.
public class A_Class_Name{
// Variables
public static string a_Variable {get;set;}
// Constructor
public A_Class_Name(){
// Constructor business logic code
}
// Methods
public void a_Method_Name(Integer a_Variable1, Ingeter a_Variable2){
// Business logic code
}
}
