Can I pass an ArrayList of custom objects as a parameter in Java?
Yes, you can pass an ArrayList of custom objects as a parameter in Java. Ensure that the object class is serializable.
What is the difference between passing ArrayList by value and by reference?
In Java, ArrayLists are passed by reference, meaning that changes made to the ArrayList within a method will reflect in the calling code.
Are there any limitations when passing ArrayLists as parameters?
While passing ArrayLists as parameters is powerful, be mindful of memory consumption when dealing with large ArrayLists.
Can I pass multiple ArrayLists as parameters to a single method?
Yes, you can pass multiple ArrayLists as parameters to a single method by defining the method with multiple ArrayList parameters.
How can I handle ArrayList parameter passing in multi-threaded applications?
To ensure thread safety, consider using synchronized blocks or concurrent data structures when passing ArrayLists in multi-threaded applications.
Is it possible to pass an ArrayList from one class to another?
Yes, you can pass an ArrayList from one class to another in Java by using method parameters or constructors.
