How to merge two objects in Java?

To merge two Java objects, you can use one of the following methods:

1. Using inheritance: If two objects have the same properties and methods, you can create a new class that inherits from the parent class of these two objects and implement the merging logic in this class.

public class MergedObject extends ParentObject {
    private String newProperty;

    public MergedObject(ParentObject obj1, ParentObject obj2) {
        super(obj1.getProperty1(), obj2.getProperty2());
        this.newProperty = obj1.getProperty3() + obj2.getProperty4();
    }

    // getter and setter for newProperty
}

1. By utilizing composition: If two objects do not have a direct relationship, you can create a new class that includes these two objects as its member variables, and implement the merging logic within that class.

public class MergedObject {
    private Object1 obj1;
    private Object2 obj2;

    public MergedObject(Object1 obj1, Object2 obj2) {
        this.obj1 = obj1;
        this.obj2 = obj2;
    }

    // Merge logic here using obj1 and obj2
}

These are just some examples, the specific merging logic depends on your needs. You may need to adjust these sample codes based on the specific situation.
