- Introdution :
Algorithm:
1. Create an object class with the data fields from the text file.
2. Read the text file line by line and store each line into an array.
3. Create an object from the object class with the values from the array.
4. Store the object into an array.
5. Create a linked list.
6. Iterate through the object array and add each object to the linked list.
- Explanation of Code:
The object class is used to create objects that store the data from the text file. The fields of the object class are the same as the data fields in the text file. Then the text file is read line by line and each line is stored in an array. An object is created with the values from the array and stored in an array of objects. Then a linked list is created and the array of objects is iterated through, adding each object to the linked list.
Parsing a Text File: Parsing a text file is the process of reading the file line by line and extracting the data from it. To parse a text file you need to use a library such as Apache Commons IO or Scanner.
Creating an Object Array: Object arrays are used to store multiple objects in one array. To create an object array, you need to use the new keyword followed by the object type and the array size. For example, Person[] people = new Person[4];
Storing Objects in a Linked List: Linked lists are data structures used to store objects in a linked list format. To store an object in a linked list, you need to create a Node object and set the data field to the object you want to store. Then you need to add the Node to the linked list.
Java Programming Language: Java is an object-oriented programming language used to write programs. To write a program in Java you need to use classes, methods, and variables. Java also provides data structures such as arrays, linked lists, and maps to help you store and manipulate data.
