To declare a class in Java, you must use the class keyword followed by the name of the class. Below are examples of how to declare a class in Java:
Example 1: Simple Class Declaration
public class MyClass {
// Class Body
}
Example 2: Class Declaration with a Private Field and Public Method
public class Person {
private String name;
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
Example 3: Class Declaration with Constructor
public class Car {
private String color;
private String make;
public Car(String color, String make) {
this.color = color;
this.make = make;
}
public String getColor() {
return color;
}
public String getMake() {
return make;
}
}
Example 4: Class Declaration with Inheritance
public class Animal {
public void eat() {
System.out.println("The animal is eating.");
}
}
public class Dog extends Animal {
public void bark() {
System.out.println("Woof woof!");
}
}
Example 5: Class Declaration with Interfaces
interface Employee {
void setSalary(double salary);
double getSalary();
}
public class Manager implements Employee {
private double salary;
public void setSalary(double salary) {
this.salary = salary;
}
public double getSalary() {
return salary;
}
}
