Compiling Java in terminal gives illegal character errors within a string

I am new and just trying to do the most basic of all, simple 'Hello World'

Here is the code, The same you find anywhere:

class HelloWorld {
    public static void main (String args[]) {
        System.out.println(“Hello World!”);
    }
}

When I run in the terminal (I use a Mac) I am posed with the following errors:

HelloWorld.java:3: error: illegal character: '\u201c'
    System.out.println(“Hello World!”);
                       ^
HelloWorld.java:3: error: ';' expected
        System.out.println(“Hello World!”);
                        ^
HelloWorld.java:3: error: not a statement
        System.out.println(“Hello World!”);
                                  ^
HelloWorld.java:3: error: ';' expected
        System.out.println(“Hello World!”);
                                       ^
HelloWorld.java:3: error: illegal character: '\u201d'
        System.out.println(“Hello World!”);
                                        ^
5 errors

What is going on here? All the errors are the string!
