Java Generics and Stack Quiz

Generics in Java

• The primary purpose of generics in Java is to provide type safety, which means to ensure that the correct type of object is used.

ClassGeneric

• The ClassGeneric class is a generic class, which means it can work with any data type.

Methods in ClassGeneric

• The 'print' method in the ClassGeneric class is used to print the value of the object.

Print Method

• The output of the 'objG2.print()' method depends on the implementation of the 'print' method in the ClassGeneric class.

Advantages of Generics

• The primary advantage of using generics in Java is to provide type safety, which helps to avoid ClassCastException at runtime.

Queue Data Structure

• A queue is a data structure that uses the mechanism of First-In-First-Out (FIFO).

Queue Operations

• In a queue, a new element is added to the rear end.
• The 'dequeue' operation is responsible for removing an element from the front end of a queue.
• The front end of a queue is used for deleting an element.
• The 'enqueue' operation is responsible for adding an element to the rear end of a queue.

IsFull Operation

• The 'IsFull()' operation in a queue is used to check if the queue is full.

Implementing Queue

• A queue can be implemented using a static array with a generic data type.
• When a new element is inserted in a queue, the front end remains the same.
• The primary advantage of using generics in Java for implementing a queue is to provide type safety, which helps to avoid ClassCastException at runtime.
