Question

Use the Bicycle.java file from Lab 4.

public class Bicycle {

// Instance field
private String ownerName;
private int licenseNumber;

// Constructor
public Bicycle( String name, int license ) {
   ownerName = name;
   licenseNumber = license;
}

// Returns the name of this bicycle's owner
public String getOwnerName() {

return ownerName;
}

// Assigns the name of this bicycle's owner
public void setOwnerName( String name ) {

ownerName = name;
}

// Returns the license number of this bicycle
public int getLicenseNumber() {

return licenseNumber;
}

// Assigns the license number of this bicycle
public void setLicenseNumber( int license ) {

licenseNumber = license;
}

}

In the Bicycle class you must add a toString method that returns a String containing the owner’s name and license number, clearly labeled. The toString method should call the get methods.

public String toString()

Create a new BicycleTest program. In the program create an array of Bicycles size 4. Create 4 Bicycle objects and assign them to the array. Put your own name as one of the owners. Then use a for loop to walk through the array and output the owner’s name and license number of each Bicycle. Do this by calling the toString method using each array element.

public class Bicycle {
   // Instance field
   private String ownerName;
   private int licenseNumber;

   // Constructor
   public Bicycle(String name, int license) {
       ownerName = name;
       licenseNumber = license;
   }

   // Returns the name of this bicycle's owner
   public String getOwnerName() {
       return ownerName;
   }

   // Assigns the name of this bicycle's owner
   public void setOwnerName(String name) {
       ownerName = name;
   }

   // Returns the license number of this bicycle
   public int getLicenseNumber() {
       return licenseNumber;
   }

   // Assigns the license number of this bicycle
   public void setLicenseNumber(int license) {
       licenseNumber = license;
   }

   /*

   */
   @Override
   public String toString() {
       return "Owner Name=" + ownerName + ", License Number=" + licenseNumber;
   }

}

/**

public class BicycleTest {

   /**

   */
   public static void main(String[] args) {
       // TODO Auto-generated method stub
       try {
           // Bicycles size 4
           Bicycle bicycles[] = new Bicycle[4];
           // 4 Bicycle objects assigning to the array
           bicycles[0] = new Bicycle("Srinivas Palli", 580);
           bicycles[1] = new Bicycle("Rajesh", 580);
           bicycles[2] = new Bicycle("Kishore", 580);
           bicycles[3] = new Bicycle("Pavan", 580);
           // use a for loop to walk through the array and output the owner’s
           // name and license number of each Bicycle
           for (Bicycle b : bicycles) {

               System.out.println(b);
           }

       } catch (Exception e) {
           // TODO: handle exception
       }
   }
}

OUTPUT:

Owner Name=Srinivas Palli, License Number=580
Owner Name=Rajesh, License Number=580
Owner Name=Kishore, License Number=580
Owner Name=Pavan, License Number=580
