### Java Operators - Practice Programs with Solutions

//Exercise 1: Arithmetic Operations

public class ArithmeticOperations {

public static void main(String[] args) {

int a = 20;

int b = 5;

int sum = a + b;

int difference = a - b;

int product = a * b;

int quotient = a / b;

int remainder = a % b;

System.out.println("Sum: " + sum);

System.out.println("Difference: " + difference);

System.out.println("Product: " + product);

System.out.println("Quotient: " + quotient);

System.out.println("Remainder: " + remainder);

}

}

//Exercise 2: Swapping Values

public class SwapValues {

public static void main(String[] args) {

int x = 10;

int y = 20;

// Swapping using arithmetic operators

x = x + y;

y = x - y;

x = x - y;

System.out.println("After swapping:");

System.out.println("x = " + x);

System.out.println("y = " + y);

}

}

//Exercise 3: Area and Perimeter of a Rectangle

public class Rectangle {

public static void main(String[] args) {

double length = 15.5;

double width = 10.0;

double area = length * width;

double perimeter = 2 * (length + width);

System.out.println("Area: " + area);

System.out.println("Perimeter: " + perimeter);

}

}

//Exercise 4: Convert Celsius to Fahrenheit

public class TemperatureConversion {

public static void main(String[] args) {

double celsius = 25.0;

double fahrenheit = (celsius * 9/5) + 32;

System.out.println(celsius + " Celsius is equal to " + fahrenheit + " Fahrenheit.");

}

}

//Exercise 5: Simple Interest Calculation

public class SimpleInterest {

public static void main(String[] args) {

double principal = 10000;

double rate = 5; // Interest rate per year in percentage

double time = 3; // Time in years

double simpleInterest = (principal * rate * time) / 100;

System.out.println("Simple Interest: " + simpleInterest);

}

}

//Exercise 6: Calculate the Average

public class AverageCalculator {

public static void main(String[] args) {

double num1 = 8.5;

double num2 = 6.7;

double num3 = 9.2;

double average = (num1 + num2 + num3) / 3;

System.out.println("Average: " + average);

}
