The difference between functions in Java and Lisp is: Declaration: Java uses keyword declaration, while Lisp uses defun keyword. Parameters and return values: Java types are explicit, Lisp types are dynamic. Invocation: Java uses parentheses, Lisp uses prefix notation. Scope: Java is block scope, Lisp is lexical scope.
Differences between Java functions and Lisp functions
In Java and Lisp, functions are blocks of code that accept Input and return output. But despite this similarity, there are some key differences between the functions of the two languages.
Declaration
public static
keyword to declare a static method, use public
Keyword declares non-static methods. defun
keyword. Parameters and return values
Calling
Scope
Practical case
The following code example demonstrates the difference between the Java function and the Lisp function for finding the Fibonacci sequence:
Java function:
public static int fibonacci(int n) { if (n == 0 || n == 1) { return 1; } else { return fibonacci(n - 1) + fibonacci(n - 2); } }
Lisp function:
(defun fibonacci (n) (cond ((or (zerop n) (eq n 1)) 1) (t (+ (fibonacci (- n 1)) (fibonacci (- n 2))))))
As you can see, Java functions have explicit type declarations and block scope, while Lisp functions have dynamic typing and lexical scope.
