Can we call one constructor from another Constructor?

Yes ,We can call one constructor from another Constructor by using this.() method.

Look the below Example:

class  Pet
{
    int id=9;
    String type="check";
    public Pet(int id) {
this.id = id;           // “this” means this object
}
public Pet (int id, String type) {
this(id);                      // calls constructor public Pet(int id)
this.type = type;               // ”this” means this object
}
    public static void main(String[] args)
    {
        Pet p=new Pet(9,"check");
    }
}
