Question

I want to store 3 values in 1 key.
a Hashmap can only hold 1 key, 1 value, so that can not be used.
So what other ways do I have to get from the one key the Value A/B/C.

Key: String

Values: String/String/int

Answer 1

Create an object to hold your 3 values and then the new object is your value in the Key-value pair.

Here is a sample implementation:

class TripleValue {
    String A;
    String B;
    int C;

    public TripleValue(String a, String b, int c) {
        A = a;
        B = b;
        C = c;
    }
}

public static void main() {
    Map<String, TripleValue> myMap = new HashMap<String, TripleValue>(); 
    myMap.put("SomeKey", new TripleValue("String1", "String2", 10));

}
