Dart for Java Developers

Based on the provided information, here's a detailed comparison of Dart and Java syntax and features:

Entry Point

Java:

java
 
1public class Main {
2    public static void main(String[] args) {
3        System.out.println("Hello");
4    }
5}

Dart:

dart
 
1void main() {
2    print('Hello');
3}

• Dart uses a top-level main function instead of a class.
• The print function is used for output, not System.out.println.

Everything Is an Object

Java:

• Primitives like int, double, etc., are not objects. Wrappers exist (e.g., Integer).

Dart:

• All types (int, double, bool) are objects and can be used interchangeably with their object-oriented counterparts.
• Example:

  dart
   
  1int num = 42;
  2double decimal = 3.14;
  3bool isTrue = true;
  4
  5num value = 5; // Can assign an integer to a variable of type 'num'

Semicolons

Java:

• Required for statement termination.
