constructor query

Question

public class Program
{
public static void main(String[] args) {
Vehicle colType = new Vehicle();
Vehicle v1 = new Vehicle("LEATHER");
colType.setColor();
System.out.println("final color :" + colType.getColor());

}
}

public class Vehicle
{
private String color;

Vehicle(String seatType){
System.out.println("seat material:" + seatType);
}

public void setColor(){
this.color = "red";
}

public String getColor(){
return color;
}
}

please let me know what am i doing wrong ? can't we declare an object "colType "to Vehicle class when constructor is defined?

Answer 1

A default constructor is only supplied if no Constructor was created for the class. Here you created one that takes a String as its arguments. So, there is no, no argument constructor.

You will need to define one on your own, like so:
Vehicle(){}

Answer 2

Change (line 4) what is your argument?

Vehicle colType = new Vehicle("Leather");

Answer 4

Vehicle colType = new Vehicle();

here colType is normal object for Vehicle class(not for constructor.. its for setter method) .. i am not passing any argument .. cant we implement like this.? when constructor is defined , can't we have other methods in class?
