Serialize data in JSON and Deserialize in Apex

Hello Friends today post, How to serialize data in JSON or JavaScript Component and Deserialize in Apex Class...

so friends let us start........
First you create a lightning component and making some field , this post only controller part and apex code so you understand better if you create saome field and fetch data in jscontroller..

JsController code...

                Save:function(component,event,helper){                        //This is function
     
        var AcName=document.getElementById('accountdata').value; //get data
       // alert(AcName);
        var Status=document.getElementById('txtStatus').value;//get data
        var Priority=document.getElementById('Priority').value;//get data
        var Origin=document.getElementById('txtOrigin').value;//get data
        var Type=document.getElementById('txtType').value;//get data
        var Reason=document.getElementById('Reason').value;//get data
        var subject=component.find("Subject").get("v.value");//get data
     
        var objCase={                              //Seriliaze Data in Variable
            "AccName":AcName,
            "cStatus":Status,
            "cPriority":Priority,
            "cOrigin":Origin,
            "cType":Type,
            "cReason":Reason,
            "cSubject":subject
         
        }
        //alert('Serialize data'+JSON.stringify(objCase));
        var action=component.get("c.SaveCase");
        action.setParams({                                                 //Set Parameter when used in Apex Class
            "caseData":JSON.stringify(objCase)               //Set Parameter when used in Apex Class
        });
        action.setCallback(this,function(a){
         
            if(a.getState()=="SUCCESS"){
                // alert(JSON.stringify(a.getReturnValue()));
                //alert("Case Successfully Created!");
                component.set("v.Second","slds-hide");
                component.set("v.Third","slds-show");
            }else{
                alert("error");
            }
        });
        $A.enqueueAction(action);
    }


=> Apex side Code for Deserialize data for use.......


public class CaseCreationController {
 
    public class caseDataContainer{
     
        @AuraEnabled  public String AccName{get;set;}
        @AuraEnabled  public String cStatus{get;set;}
        @AuraEnabled  public String cPriority{get;set;}
        @AuraEnabled  public String cOrigin{get;set;}
        @AuraEnabled  public String cType{get;set;}
        @AuraEnabled  public String cReason{get;set;}
        @AuraEnabled  public String cSubject{get;set;}
     
    }
@AuraEnabled
    public static String SaveCase(String caseData){
     
        System.debug('Direct data from js=>'+caseData);
       // List<caseDataContainer> serdata=new List<caseDataContainer>();
       caseDataContainer data =(caseDataContainer)System.JSON.deserialize(caseData,caseDataContainer.class);  //This code is Deserialize Data and use for Create Case
     
        System.debug('Case data=>'+data);
     
        String result='';
     
        try{
            Case obj=new Case();
            obj.AccountId=data.AccName;
            obj.Status=data.cStatus;
            obj.Priority=data.cPriority;
            obj.Origin=data.cOrigin;
            obj.Type=data.cType;
            obj.Reason=data.cReason;
            obj.Subject=data.cSubject;
         
            insert obj;
            result=obj.Id;
        }catch(Exception e){
            System.debug('Error is' +e.getMessage()+ 'in Line '+e.getLineNumber());
        }
     
        return result;
     
    }
