Java week 2 Question 1 code

Java week 2 Question 2 code

// Write the appropriate constructor call code in the given spaces .
//Good luck

if (grade == null ||grade.isEmpty()) {
student = new Student(name,age); // Add your code to call the constructor when grade is not given in input
} else {
student = new Student(name,age,grade); // Add your code to call the constructor when grade is given in input
}

// code to call displayInfo function to display the information
student.displayInfo(); // Call the displayInfo method to display the student’s information

Java week 2 Question 3 code

// Define the class Rectangle here
// Use the this keyword in the constructor
// Define the area method

class Rectangle {
int length, breadth;

// Constructor
Rectangle(int length, int breadth) {
this.length = length;
this.breadth = breadth;
}

// Method to calculate area
int area() {
return length * breadth; //write the correct formula
}
}

//I hope it will work

Java week 2 Question 4 code

// Define the class Car here
// Write a constructor and a display method
//ok

class Car {
//variables
String brand;
int price;

// Constructor
Car(String brand,int price) {
this.brand=brand;
this.price=price;
}

// Display method
void display(int num) {
System.out.println(“Car ” + num + “: ” + brand + “, Price: ” + price);
}
}

Java week 2 Question 5 code

//Let us see

class Book {
// Private attributes
private String title;
private String author;

// Setter for title
public void setTitle(String title) {
this.title = title;
}

// Setter for author
public void setAuthor(String author) {
this.author=author;
}

// Getter for title
public String getTitle() {
return this.title;
}

// Getter for author
public String getAuthor() {
return this.author;
}
