🧪 Day 1: Java Datatypes Practice

📌 Program: Mydetails.java

This program demonstrates the use of different Java datatypes by storing and printing personal details.

🔢 Datatypes Used

• String → Name
• int → Age
• byte → Number of siblings
• long → Phone number
• float → Height
• double → Weight
• boolean → Student status

🎯 Output

The program prints formatted personal information using different datatypes.

💡 Key Learning

• Understood primitive and non-primitive datatypes
• Learned how to store and display values
• Practiced basic Java syntax and structure

Voting Eligibility Checker

This is a simple Java program that checks whether a person is eligible to vote using basic if conditions.

📌 Description

The program takes a person's age as input and determines if they are allowed to vote or not. If the age is 18 or above, the person is eligible to vote. Otherwise, they are not eligible.

⚙️ Features

• Uses simple if condition
• Easy to understand logic
• Beginner-friendly program

🛠️ Technologies Used

• Java

▶️ How It Works

1. Enter age

2. Program checks condition:

   • If age ≥ 18 → Eligible to vote
   • Else → Not eligible

Voting Eligibility Checker 🗳️

📌 Description

This is a simple Java program that checks whether a person is eligible to vote based on their age using conditional statements.

🚀 Features

• Uses basic if-else condition
• Beginner-friendly Java program
• Demonstrates decision-making logic

🧠 Logic

• If age is greater than or equal to 18 → Eligible to vote
• Otherwise → Not eligible to vote

💻 Code Example

class Result {
    public static void main(String[] args) {
        int age = 20;

        if (age >= 18) {
            System.out.println("The person is eligible to vote");
        } else {
            System.out.println("The person is not eligible to vote");
        }
    }
}

▶️ How to Run

1. Save the file as Result.java

2. Open terminal in the file location

3. Compile the program:

   javac Result.java
   

4. Run the program:

   java result
   

📊 Example Output

The person is eligible to vote

🛠️ Technologies Used

• Java

🎯 Purpose

This project is created as part of learning Java fundamentals and improving programming logic for coding interviews.

Income Eligibility Checker (Java)

This is a simple Java program that checks whether a student is eligible for a scholarship based on their income.

📌 Description

The program takes a fixed income value and uses an if-else condition to determine eligibility.

• If income is greater than 7000 → Scholarship Available
• Otherwise → Not eligible for scholarship

💻 Technologies Used

• Java
• Basic If-Else Statement

▶️ How to Run

1. Compile the program: javac Income.java

2. Run the program: java Income

📂 Sample Output

Not eligible for scholarship

🎯 Purpose

This program is useful for beginners to understand:

• Conditional statements in Java
• Basic program structure

Divisibility Checker (Java)

This is a simple Java program that checks whether a number is divisible by both 3 and 5 using nested if statements.

📌 Description

The program initializes a number and checks:

• If the number is divisible by 3
• Then it checks if the number is also divisible by 5

If both conditions are satisfied, it prints that the number is divisible by both 3 and 5.

💻 Technologies Used

• Java
• Nested If-Else Statements

▶️ How to Run

1. Compile the program: javac Divisible.java

2. Run the program: java Divisible

📂 Sample Output

Number is divisible by both 3 and 5

⚠️ Note

The current program only prints output when the number is divisible by both 3 and 5. If the number is divisible by 3 but not by 5, no output will be shown.

🎯 Purpose

This program helps beginners understand:

• Nested if conditions
• Modulus operator (%)
• Logical checking in Java
