apex code logic

1=list<String> firstcolourlist=new list<String>{'red','blue','yellow','orange','blue','red'};
    2=  list<String>secondcolourlist=new list<String>{'blue','black','yellow','green','blue'};

if we compare list1 - list2 or list2 - list1  we have to print common values in both lists along with their count

Hi Chaitanyakuamar,

Please execute the following lines of code to get the required output:

List<String> Flist = new list<String>{'red','blue','yellow','orange','blue','red'};
    List<String> Slist = new list<String>{'blue','black','yellow','green','blue'};
        List<String> CommonValueList = new list<String>();
for(String var : Flist){
    if(Slist.contains(var) && !CommonValueList.contains(var)){
        CommonValueList.add(var);
    }
}
        List<String> MergedList = new list<String>();
MergedList.addAll(Flist);
MergedList.addAll(Slist);
Map<String, List<String>> requiredMap = new Map<String, List<String>>();
for(String obj : MergedList){
    if(requiredMap.containsKey(obj)){
        requiredMap.get(obj).add(obj);
    }else{
        requiredMap.put(obj,new list<String>());
        requiredMap.get(obj).add(obj);
    }
}
// Commonvaluelist contains the common values and iterate it over map to get the count values
for(String x: CommonValueList){
    System.debug(x +' : '+requiredMap.get(x).size());
}


I hope you find the above solution helpful. If it does, please mark it as Best Answer to help others too.
