Array of Objects
An array of objects is created just like an array of primitive type data items in the following way.
Car[] model = new Car[5];
The above statement creates the array which can has length of five objects. It doesn’t create the objects themselves. They have to be created separately, in the following complete example.
Example
class Car {
int gears;
}
public class ObjectsExample {
public static void main(String[] args) {
Car[] model = new Car[5]; // 5 is length of array
for (int a = 0; a < 5; a++) {
model[a] = new Car(); // allocating memory to arrays one by one
model[a].gears = a + 1; // assigning values
}
// Printing array elements
for (int a = 0; a < 5; a++) {
System.out.print("Object = model[" + a + "]");
System.out.println(" Gears = " + model[a].gears);
}
}
}
Output
Object = model[0] Gears = 1 Object = model[1] Gears = 2 Object = model[2] Gears = 3 Object = model[3] Gears = 4 Object = model[4] Gears = 5
