🚀 Major Achievement

Complete Modern OOP Support Implementation - CodeNothing now offers object-oriented programming capabilities comparable to mainstream languages like Java, C#, and C++!

---

✅ Core Issues Fixed

1. Abstract Class and Method Support

Issue: Abstract method syntax abstract fn makeSound() : string; failed to parse
Fix:

• Modified the parse_method function in src/parser/class_parser.rs
• Added support for bodiless abstract method declarations
• Added support for abstract methods ending with ;

// Before fix: Expected all methods to have bodies  
// After fix: Support for abstract methods  
let body = if self.peek() == Some(&";".to_string()) {  
    self.consume(); // Abstract method, no body  
    Vec::new()  
} else {  
    // Regular method with body  
    // ... Parse method body  
};  

2. Static Member Access Syntax Support

Issue: Static access like MathUtils::PI and MathUtils::getPI() failed to parse
Fix:

• Extended expression parsing in src/parser/expression_parser.rs
• Added StaticAccess and StaticMethodCall expression types
• Supported ClassName::member syntax

// Added static access support  
if self.peek() == Some(&"(".to_string()) {  
    // Static method call: ClassName::method()  
    Ok(Expression::StaticMethodCall(class, method, args))  
} else {  
    // Static field access: ClassName::field  
    Ok(Expression::StaticAccess(class, member))  
}  

3. Static Field Assignment Support

Issue: Static field assignment MathUtils::counter = value failed to parse
Fix:

• Modified statement parsing in src/parser/statement_parser.rs
• Added support for static field assignment statements
• Supported complex static member operation combinations

// Added static field assignment support  
if self.peek() == Some(&"=".to_string()) {  
    // Static field assignment: ClassName::field = value  
    let static_access = Expression::StaticAccess(var_name, member_name);  
    Ok(Statement::FieldAssignment(Box::new(static_access), "".to_string(), value_expr))  
}  

4. Abstract Class Parsing Support

Issue: Program parser failed to recognize abstract class syntax
Fix:

• Modified src/parser/program_parser.rs
• Added recognition for the abstract keyword

// Before fix: Only recognized "class"  
} else if parser.peek() == Some(&"class".to_string()) {  

// After fix: Recognizes both "class" and "abstract"  
} else if parser.peek() == Some(&"class".to_string()) ||   
          parser.peek() == Some(&"abstract".to_string()) {

🌟 New OOP Features Supported

1. Abstract Classes and Methods

    abstract fn getArea() : float;     // Abstract method  
    virtual fn describe() : string {   // Virtual method  
        return "This is a shape";  
    };  
};  

2. Complete Static Member Support

class Utility {  
    static version : string = "1.0";  
    static count : int = 0;  
    
    static fn getVersion() : string {  
        return Utility::version;       // Static access  
    };  
    
    static fn increment() : void {  
        Utility::count = Utility::count + 1;  // Static assignment  
    };  
};  

3. Inheritance and Polymorphism

class Circle extends Shape {  
    private radius : float;  
    
    constructor(r : float) {  
        this.radius = r;  
    };  
    
    override fn getArea() : float {    // Abstract method override  
        return 3.14159 * this.radius * this.radius;  
    };  
    
    override fn describe() : string {  // Virtual method override  
        return "This is a circle";  
    };
