JAVA - Error while comparing Object items

I have the following code

set1.forEach( k -> {
   for (String s : set2) {
        if(s.split(";")[0].equals(k){
            //do something
        }
    }
...

but I have this error

k cannot be resolved to a variable

Is there a way to read this variable?

Thanks

You missed one paranthesis after k. You should have two closed paranthesis as below near equals 

    Set<String> set1 = new HashSet<>();

    Set<String> set2 = new HashSet<>();

    set1.forEach((k)-> {
        for (String string : set2) {
            if(string.split(":")[0].equals(k)){
                //do something
            }

        }
    });
