How do define my own element class for use with Set

Question

I have the following code:

public class MyElement {
    String name;
    String type;

    MyElement(String name, String type) {
        this.name = name;
           


        

Answer 1

You should override an equals(MyElement me) function. Equals returns a boolean

Otherwise, you are checking that two items are the same instance of an object, not that their internal content is the same.

MyElement(String name, String type) {
    this.name = name;
    this.type = type;
}

public boolean Equals(MyElement me) {
    return this.name.equals(me.name) && this.type.equals(me.type);
}
