Hands-On Object-Oriented Programming with Kotlin

Java classes in Kotlin

Let's explore how to create a Java class object in Kotlin. To do this, create a Shape.java file with three properties: height, width, and name with getters and setters:

public class Shape {    private int width;    private int height;    public static final double PI = 3.1415;    private final String name;    public Shape(int width, int height, String name) {        this.width = width;        this.height = height;        this.name = name;    }    public final int getHeight() {        return this.height;    }    public final void setHeight(int value) {        this.height = value;    }    public final String getName() {        return this.name;    }    public final void shapeMessage() {        System.out.println("Hi i am " + this.name + ", how are you doing");    }}
