java-hacktoberfest23's Issues

Write a Java program to create a package which has classes and methods to read Student Admission details.

Merge sort in Java

I want to add the implementation of trie (prefix tree) data structure

Solve Question 2

Write a class Account which should have a private instance variable called balance. Create gettter and setter methods for balance variable. Also write two methods
with the following signature –
void deposit(int amt)
void withdraw(int amt)

withdraw method should give a message insufficient amount if the amount you are trying to withdraw is more than current balance otherwise balance need to be reduced
by the amount withdrawn.

Create another class TestAccount and write down main method there. Create an object of Account class. Start the account with Rs 2000. Add Rs 500 and withdraw Rs 1800. Then show the balance.

Overloading 1.0

• Create a class 'Student' with three data members which are roll, name, marks and address. The constructor of the class assigns default values roll as "not assigned", name as "unknown", marks as '0' and address as "not available". It has three methods with the same name 'getData'. First method has two parameters for name and roll and assigns the same whereas the second method has four parameters which are assigned to name, roll, marks and address respectively. Defined another method to print the student details. create three objects and print the details of these student Objects.

• Implement the above program using Constructor Overloading.

This files describe how to fork , clone, create branch, commit message, and push to the repository which is followed inorder to get their PRs merged.

Create a class to print the area of a square and a rectangle. Use methods to assign the values and print the details.

Solve question 3.4

Create a class named 'School' with the following data members

1 –Roll no of Student
2 –Name of Student
3 - Address

Class 'School' has a method for the following

The program will support the following menu based activities: do the following operations:
Number of students are to be entered by user. Depending upon the number of students, enter the information (name, address, type of account, balance) for each student.

Q. Print the information of a particular student.

Terminal/console based project on Task Manager and Remainder System.

This project should completely run in terminal and should be purely programmed with Java.

Your program needs to solve two important needs of this project, they are:

• Task Manager: The program should take input from the user to create tasks, view tasks, mark task as completed and exit.
• Task Remainder: Should contain remainder system. When a task doesn't get completed it should display "Task is due!" without any actions done by the user.

You can customize your project in whichever way you want. Don't forget to solve the two important needs.

Thank You.

Understanding Types of Inheritance in Java

Description:

This GitHub issue is aimed at providing a comprehensive explanation and examples of the various types of inheritance in Java. Inheritance is a fundamental concept in object-oriented programming that allows one class (subclass) to inherit attributes and methods from another class (superclass). There are several types of inheritance, each with its own unique

1. Single Inheritance: In this type, a subclass inherits from only one superclass. This is the simplest form of inheritance.

2. Multilevel Inheritance: In this type, a subclass inherits from a superclass, and another class inherits from this subclass. This creates a hierarchy of classes.

3. Hierarchical Inheritance: In this type, multiple subclasses inherit from the same superclass. This allows for the creation of specialized classes with shared attributes and methods.

4. Multiple Inheritance (through Interfaces): While Java does not support multiple inheritance of classes, it does allow a class to implement multiple interfaces. This allows a class to inherit method signatures from multiple sources.

5. Hybrid (Combination of any two types of inheritance): Java allows for combinations of the above types, such as a mix of single and multiple inheritance.

The goal of this issue is to create a detailed explanation for each type of inheritance, along with clear and concise code examples. Contributors are encouraged to provide well-commented code snippets and explanations to help readers grasp the concepts effectively.

Contribution Guidelines:

• Please make sure to follow proper code formatting conventions (e.g., indentation, naming conventions).
• Provide detailed comments to explain the code logic.
• Ensure that the examples are clear and easy to understand for learners of various levels.

Repository Structuring in proper format

This issue is raised to address the formatting and code structure concerns within the repository. The current organization of files and code is not following best practices, which can make it challenging for contributors and users to navigate and utilize the content effectively.

To improve the repository, we should consider the following actions:

1. Define Clear Structure: We need to define a clear and consistent structure for the repository. This includes organizing code according to the programming language.

2. Standardize File and Folder Names: Standardize the naming conventions for files and folders to make them more descriptive and easier to understand.

3. Remove Unnecessary Files: Identify and remove irrelevant files like .DS_Store and .gitgnore. Keep the repository clean and free from clutter.

By addressing these issues, we can enhance the overall quality and usability of the repository. Please feel free to share your thoughts and suggestions on how we can achieve these improvements effectively. Your input is valuable in making this repository more accessible and user-friendly for all.
