[java] Add an object to an Array of a custom class

Im a beginner to Java and I'm trying to create an array of a custom class. Let say I have a class called car and I want to create an array of cars called Garage. How can I add each car to the garage? This is what I've got:

car redCar = new Car("Red");
car Garage [] = new Car [100];
Garage[0] = redCar;

The array declaration should be:

Car[] garage = new Car[100];

You can also just assign directly:

garage[1] = new Car("Blue");

If you want to create a garage and fill it up with new cars that can be accessed later, use this code:

for (int i = 0; i < garage.length; i++)
     garage[i] = new Car("argument");

Also, the cars are later accessed using:

garage[0];
garage[1];
garage[2];
etc.
