Hard to make suggestions without seeing a complete example of the current
state of affairs, but let me try - after pointing you to
<http://www.physci.org/codes/sscce.html>
for next time.

package example;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;

public class Car
{
  private String type;
  private String color;
  private String description;
  private String make;

  public void setType( String val )        { type = val; }
  public String get()     { return type; }

  public void setColor( String val )       { color = val; }
  public String get()     { return color; }

  public void setDescription( String val ) { description = val; }
  public String get()     { return description; }

  public void setMake( String val )        { make = val; }
  public String get()     { return make; }

  public static void main( String [] args )
  {
    if ( args.length < 2 )
    {
      System.err.println( "Wrong args" );
      return;
    }

    Scanner carIn;
    try
    {
      carIn = new Scanner( new BufferedReader( new FileReader( args [0] )));
    }
    catch ( IOException ex )
    {
      System.err .println( "Bad File "+ args [0] +". "+ ex.getMessage() );
      ex.printStackTrace( System.err );
      return;
    }

    Car[] cars;
    {
      int nc;
      try
      {
        nc = Integer.parseInt( args [1] );
        if ( nc < 0 )
        {
           nc = 50;
        }
      }
      catch ( NumberFormatException ex )
      {
        nc = 50;
      }
      cars = new Car [nc];
    }

    try
    {
      for ( int ix = 0; ix < cars.length && carIn.hasNext(); ++ix )
      {
        Car car = new Car();

        String val = carIn.next();
        car.setType( val );

        val = carIn.next();
        car.setColor( val );

        val = carIn.next();
        car.setDescription( val );

        val = carIn.nextLine();
        car.setMake( val );

        cars [ix] = car;
      }

      // do something here with cars
    }
    finally
    {
      carIn.close();
    }
  }

}
