How to return multiple objects from a Java method

Question

What are the possible ways to return the number of objects from a method in Java?

Answer 1

Yes, we can return multiple objects from a method in Java as the method always encapsulates the objects and then returns.
You can return a list of objects like:

public class CustomObject<Obj> {
  public final int id;
  public final Obj customObject;

  public CustomObject(int id,Obj customObject) {
    this.id = id;
    this.customObject = customObject;
  }
}

and return this as List<CustomObject<DataType you want>>

In the event the method you're calling is private, or called from one location, try

return new Object[]{value1, value2};

The caller looks like:

Object[] temp=myMethod(parameters);Type1 value1=(Type1)temp[0];  //For code clarity: temp[0] is not descriptiveType2 value2=(Type2)temp[1];
