Why do C# and Java bother with the “new” operator?

Why does java have the new keyword? To create an object of type A, I have to type A a = new A().

Java doesn’t have stack allocation, so why couldn’t that just be simplified to A a = A()?

Answer 1

Because C++ did it so, I presume. Java was supposed to look superficially like C++, but with a greatly simplified and streamlined language.

In any case, you got a problem there:

class Foo {
   private static void A() {
     System.out.println("method");
   }

   public static void main(String[] args) {
     A();
   }
}

class A {
  public A() {
    System.out.println("ctor");
  }
}

What should happen here? ctor or method?
