How to merge two objects in Java?
To merge two Java objects, you can use one of the following methods:
- 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
}
- 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.
