List<Contact> contactList=[select id,accountid from Contact where accountid!=null];
        map<Id,List<Contact>> contactMap=new map<Id,List<Contact>>();
        for(Contact con:contactList){
        list<Contact>conList = new list<Contact>();
            if(contactMap.containsKey(con.accountid)){
                conList = contactMap.get(con.accountid)
            }
            conList.add(con);

Hello Pc,

You can try below code,

public class InsertCaseMap {
    public static void methForCase(){
       Map<Case,list<Case>> caseslist=new Map<Case,list<Case>>();
       list<Case> caselist=[SELECT id,(SELECT id from Cases) FROM Case];
        for(Case cs:caselist){
            caseslist.put(cs,cs.Cases);
        }
        system.debug(caseslist);
    }
}

Hope this will help you.
Thanks.
