Pass a vlalue from a trigger to a class and return a value from the class back to the trigger

Is this possible?

from the trigger:

//call out to the class
returnStateAbbreviations f = new returnStateAbbreviations();
f.returnStateAbbreviations(stateName);

//attempt to return from class
 public with sharing class returnStateAbbreviations 
{  
    public string returnState(string stateName)
    { 
        String abbr;
        String stateAbbr;
        
        if(stateName=='Alabama')
        {
            stateAbbr = 'AL';            
        } //
// etc
        abbr = stateAbbr;
        return abbr;        
    }  

}

how would I then receive abbr back at the trigger?

Hi Tony,

These should be the lines of code to be used.

Trigger -  
//call out to the class
returnStateAbbreviations f = new returnStateAbbreviations();
String abbrFromClass;
abbrFromClass = f.returnState(stateName);

Class -  
//attempt to return from class
public with sharing class returnStateAbbreviations 
{  
    public string returnState(string stateName)
    { 
        String abbr;
        String stateAbbr;
        
        if(stateName=='Alabama')
        {
            stateAbbr = 'AL';            
        } 
        abbr = stateAbbr;
        return abbr;        
    }  
}

Thanks

You class returnStateAbbreviations has method named returnState and hence the line in your trigger should be f.returnState(stateName);
