Question

Say I have a class with multiple private String variables:

public class Children
{
    private String child0, child1;
}

I want to create a SetName method, which would set child0 or child1 to a specified value

So I could do something like this after instantiating Children class:

myChildren.SetName(child0, "Lucy");

How can I pass the private class variable String in a method? How do I code SetName method? I know I could create an array, and pass the element number, but that’s not what I need, not how I want to implement this.

You could store the children in one of Map‘s implementation. HashMap is appropriate for most cases.

public class Children
{
    private Map<String, String> children = new HashMap<String, String>();

    public void SetName(string child, string name)
    {
        children.put(child, name);
    }
}
