Learn Java from Scratch - A Beginner's Guide - Step 10 - List and ArrayList - Sorting - Introduction to Collections Sort

The video tutorial covers sorting techniques in Java, starting with sorting a list of integers using ArrayList and Collections.sort. It then progresses to creating a custom Student class with attributes and methods, including constructors and getters/setters. Finally, it explains how to sort a list of custom objects by implementing the Comparable interface, highlighting the importance of defining comparison logic for custom classes.

What is required to use the default sort method in the List interface?

• A comparator

• An iterator

• A filter

• A transformer

Which method is commonly used to sort an ArrayList in Java?

• ArrayList.sort

• Arrays.sort

• List.sort

• Collections.sort

What is the first step in creating a new Java project in Eclipse?

• Create a new class

• Generate getters and setters

• Implement the Comparable interface

• Create a new Java project

What is the purpose of the toString method in the Student class?

• To compare two Student objects

• To sort the Student objects

• To initialize the Student object

• To print the Student object in a readable format

Why is the Comparable interface necessary for sorting custom objects?

• To enable object serialization

• To implement custom constructors

• To allow objects to be printed

• To provide a default sorting order

What method must be implemented when using the Comparable interface?

• compareTo

• equals

• toString

• hashCode

What is the main reason for using ArrayList in the examples?

• It is the fastest collection

• It is the default choice for collections

• It is thread-safe

• It uses less memory
