Answer 1

Program:

public class Auto
{
   private String make;
   private String model;
   private int year;
  
   //default constructor
   Auto()
   {
       make="";
       model="";
       year=0;              
   }
  
   //constructor to initialize all instance variables
   Auto(String strMake,String strModel, int y)
   {
       make=strMake;
       model=strModel;
       year=y;
   }
  
   //accessor and mutators for make variable
  
   //method that returns make
   public String getMake()
   {
       return make;
   }
  
   //method that sets make
   public void setMake(String strMake)
   {
       make=strMake;
   }
  
   //method that returns model
   public String getModel()
   {
       return model;
   }
  
   //method that returns year
   public int getYear()
   {
       return year;
   }

   public static void main(String[] args)
   {
       //create an object name it myAuto with values of Toyota, Camry, and 2016
       Auto myAuto=new Auto("Toyota","Camry",2016);
      
       //print the object state using get methods
       System.out.println("Make: "+myAuto.getMake());
       System.out.println("Model: "+myAuto.getModel());
       System.out.print("Year: "+myAuto.getYear());
   }

}

Output:
