What is Java Coding Problems And Solution With Classes?

Java coding problems with classes often involve issues like object instantiation, method overriding, inheritance, and polymorphism. For example, a common problem is creating a class hierarchy for a basic geometric shape system.

Problem: Design a class Shape with subclasses Circle and Rectangle. Each subclass should implement a method to calculate the area.

Solution:

class Shape {
    public double area() {
        return 0;
    }
}

class Circle extends Shape {
    private double radius;
    
    Circle(double radius) {
        this.radius = radius;
    }
    
    @Override
    public double area() {
        return Math.PI * radius * radius;
    }
}

class Rectangle extends Shape {
    private double width, height;
    
    Rectangle(double width, double height) {
        this.width = width;
        this.height = height;
    }
    
    @Override
    public double area() {
        return width * height;
    }
}

This solution demonstrates class design, inheritance, and method overriding.
