Class Object Example

Class
Object
– Earth is a software application where human and other thing is software objects.For creating object we need to create a human class. Humans have basic behaviors as well as some basic attributes age height inches etc.

Human,java

package Prerequisite_OOP;

public class Human {
    String name;
    int age;
    int heightInInches;
    String eyeColor;

    public Human(){

    }

    public void speak(){
        System.out.println("Hello, my name is"+name);
        System.out.println("I am"+heightInInches+" inches tall");
        System.out.println("i am "+age+" years old");
        System.out.println("My eye color is "+eyeColor);
    }


    public void eat(){
        System.out.println("Eating...");
    }

    public void walk(){
        System.out.println("Walking...");
    }


    public void work(){
        System.out.println("Working");
    }

}

Earth.java

package Prerequisite_OOP;

public class Earth {
    public static void main(String[] args) {
        Human tom;
        tom=new Human();
        tom.speak();


        tom.age=5;
        tom.eyeColor="Blue";
        tom.heightInInches=72;
        tom.name="Tom Zsabo";
        tom.speak();
    }

}
