vii.3.2: Basic class use. Sample output for below program: Kids: iii New iv // ===== Code from file PersonInfo.java =====
Print person1's kids, call the incNumKids() method, and print again, outputting text as beneath. End each line with a newline.
baby, kids now:
public class PersonInfo {
private int numKids;
public void setNumKids(int personsKids) {
numKids = personsKids;
}
public void incNumKids() {
numKids = numKids + 1;
}
public int getNumKids() {
return numKids;
}
}
// ===== end =====
// ===== Code from file CallPersonInfo.java =====
public course CallPersonInfo {
public static void main (String [] args) {
PersonInfo person1 = new PersonInfo();
person1.setNumKids(three);
/* Your solution goes here */
}
}
// ===== end =====
7.three.three: Basic class definition.
Define the missing method. licenseNum is created every bit: (100000 * customID) + licenseYear. Sample output:
Dog license: 77702014 // ===== Code from file DogLicense.java =====
public class DogLicense {
private int licenseYear;
private int licenseNum;
public void setYear(int yearRegistered) {
licenseYear = yearRegistered;
}
// FIXME: Write createLicenseNum()
/* Your solution goes here */
public int getLicenseNum() {
render licenseNum;
}
}
// ===== end =====
// ===== Lawmaking from file CallDogLicense.coffee =====
public class CallDogLicense {
public static void primary (Cord [] args) {
DogLicense dog1 = new DogLicense();
dog1.setYear(2014);
dog1.createLicenseNum(777);
System.out.println("Domestic dog license: " + dog1.getLicenseNum());
}
}
// ===== end =====
7.v.1: Basic constructor definition.
Define a constructor every bit indicated. Sample output for below program:
Year: 0, VIN: -one Year: 2009, VIN: 444555666 // ===== Code from file CarRecord.java =====
public class CarRecord {
individual int yearMade;
individual int vehicleIdNum;
public void setYearMade(int originalYear) {
yearMade = originalYear;
}
public void setVehicleIdNum(int vehIdNum) {
vehicleIdNum = vehIdNum;
}
public void print() {
Arrangement.out.println("Twelvemonth: " + yearMade + ", VIN: " + vehicleIdNum);
}
// FIXME: Write constructor, initialize year to 0, vehicle ID num to -1.
/* Your solution goes hither */
}
// ===== end =====
// ===== Code from file CallCarRecord.java =====
public class CallCarRecord {
public static void main (String [] args) {
CarRecord familyCar = new CarRecord();
familyCar.print();
familyCar.setYearMade(2009);
familyCar.setVehicleIdNum(444555666);
familyCar.print();
}
}
// ===== end =====
seven.half dozen.i: Constructor overloading.
Write 2nd constructor as indicated. Sample output:
User1: Minutes: 0, Messages: 0 User2: Minutes: k, Letters: 5000 // ===== Code from file PhonePlan.java =====
public class PhonePlan {
private int freeMinutes;
individual int freeMessages;
public PhonePlan() {
freeMinutes = 0;
freeMessages = 0;
}
// FIXME: make second constructor with numMinutes and numMessages parameters.
/* Your solution goes here */
public void print() {
System.out.println("Minutes: " + freeMinutes + ", Messages: " + freeMessages);
}
}
// ===== finish =====
// ===== Code from file CallPhonePlan.java =====
public class CallPhonePlan {
public static void chief (Cord [] args) {
PhonePlan user1Plan = new PhonePlan(); // Calls default constructor
PhonePlan user2Plan = new PhonePlan(m, 5000); // Calls newly-created constructor
System.out.print("User1: ");
user1Plan.print();
Organization.out.print("User2: ");
user2Plan.print();
}
}
// ===== end =====
7.7.one: Unit testing of a grade.
Write unit of measurement test for addInventory(), which has an fault. Telephone call redSweater.addInventory() with parameter sweaterShipment. Impress the shown fault if the subsequent quantity is incorrect. Sample output for failed unit test given initial quantity is 10 and sweaterShipment is 50:
Starting time tests. UNIT Exam FAILED: addInventory() Tests complete. Note: Unit of measurement Examination FAILED is preceded by iii spaces.
// ===== Code from file InventoryTag.java =====
public class InventoryTag {
private int quantityRemaining;
public InventoryTag() {
quantityRemaining = 0;
}
public int getQuantityRemaining() {
return quantityRemaining;
}
public void addInventory(int numItems) {
if (numItems > 10) {
quantityRemaining = quantityRemaining + numItems;
}
}
}
// ===== terminate =====
// ===== Code from file CallInventoryTag.java =====
public class CallInventoryTag {
public static void main (String [] args) {
InventoryTag redSweater = new InventoryTag();
int sweaterShipment;
int sweaterInventoryBefore;
sweaterInventoryBefore = redSweater.getQuantityRemaining();
sweaterShipment = 25;
System.out.println("Beginning tests.");
// FIXME add unit test for addInventory
/* Your solution goes here */
System.out.println("Tests complete.");
}
}
// ===== end =====
vii.ix.one: The this implicit parameter.
Define the missing method. Use "this" to distinguish the local member from the parameter name.
// ===== Code from file CablePlan.java =====
public course CablePlan {
private int numDays;
// FIXME: Define setNumDays() method, using "this" implicit parameter.
public void setNumDays(int numDays) {
/* Your solution goes here */
}
public int getNumDays() {
return numDays;
}
}
// ===== end =====
// ===== Code from file CallCablePlan.coffee =====
public class CallCablePlan {
public static void main (String [] args) {
CablePlan house1Plan = new CablePlan();
house1Plan.setNumDays(thirty);
System.out.println(house1Plan.getNumDays());
}
}
// ===== stop =====
