Question

I have repeated values in my array such as Fiat, 2.3, 2006, Ford, 1.6, 2011

I’m trying to print out the values like:

Name: Fiat
Size: 2.3
Year: 2006

Name: Ford
Size: 1.6
Year: 2011

Answer 1

So you want to print out an Object array in the given format?

for(int i = 0; i < array.length-2; i += 3) {
  System.out.println("Name: " + array[i]);
  System.out.println("Size: " + array[i+1]);
  System.out.println("Year: " + array[i+2]);
}

Please note that it would really be better to use an object to hold the data on each car, rather than keeping it all in a homogenous array. Something like:

class Car {
  String name;
  double size;
  int    year;
  public Car(String _name, double _size, int _year) {
    name = _name; size = _size; year = _year;
  }
}

Then to convert your Object array into a list of Cars,

List<Car> cars = new ArrayList<Car>();
for(int i = 0; i < array.length-2; i += 3) {
  cars.add(new Car((String)array[i], (Double)array[i+1], (Integer)array[i+2]);
}

This is assuming that you are using an Object array which contains Strings, Doubles, and Integers. If it is a String array,

List<Car> cars = new ArrayList<Car>();
for(int i = 0; i < array.length-2; i += 3) {
  cars.add(new Car((String)array[i], Double.valueOf((String)array[i+1]), Integer.valueOf((String)array[i+2]));
}
