[FIXED] How to creat a set with elements from either set 1 or set 2 or both?

Issue

Hey I wanted to ask how I can add elements in a new set that either are in my set a or set b or both sets. This is what I have until now. Would be nice of you could help me.

public static Set<String> vereinigung(Set<String> a, Set<String> b) {
        Set<String> setForAB = new HashSet<String>();

        //add elements from a
        setForAB.add(String.valueOf(a));

        //add elements from a
        setForAB.add(String.valueOf(b));

        //elements from both sets
        setForAB.addAll(a);
        setForAB.addAll(b);

        return setForAB;
    }

Solution

You are on right track, removed unncessary code from your solution. This should suffice.

public static Set<String> vereinigung(Set<String> a, Set<String> b) {
        Set<String> setForAB = new HashSet<String>();
        //add elements from both sets
        setForAB.addAll(a);
        setForAB.addAll(b);
        return setForAB;
    }
