How Can we access Innerclass variables and methods in salesforce?

Question

How can we access Inner class methods or variables in salesforce from the anonymous window.Please refer the below example code:

public class OuterClass {
    public String CompanyName;
    public String CompanyAddress;
    public void PrintCompany(String CompanyName, String CompanyAddress){
        this.CompanyName = CompanyName;
        this.CompanyAddress = CompanyAddress;
        System.debug('Company name is : ' + CompanyName + '\n' + 'Company is located in : ' + CompanyAddress);
    }
        
    public class InnerClass{
        public String ModelName;
        public Integer Quantity;
        public Integer Price;
        public void Model(){
            System.debug('InnnerClass');
        }
    }
}

Anonymous window code:

OuterClass Comp = new OuterClass();
Comp.PrintCompany('Royal Enfield','Jodhpur');

So from the code I am not sure on how I can access the variables or methods in the anonymous window of the 'InnerClass' class? Also, I have given the access modifier to the inner class as public. As we cannot access private inner class outside the outer class and can be accessed inside the outer class only.

Another Question: -can we have public variables in inner class when it is defined private? As the variables cant be more restrictive than the class is my assumption correct?

Answer 1

You use the notation of outer.inner, such as:

OuterClass.InnerClass inner = new OuterClass.InnerClass();
inner.ModelName = 'Acme';
// ... etc

Note that you must create an instance of an inner class, and use that instance to access inner class variables and methods. Static methods and variables are not allowed.

Methods will be called by using the variable, called an instance of the class.

inner.model();
