What will be a simple program to explain object in java?

Answer 1

This is the Num objects class

public class Num{

public int number; // makes the integer that will store the number

public Num(int a){ //constructor

number = a; //number being stored

}

public void setNumber(int b){ //New Method that will edit number

number = b;

}

public int getNumber(){ //New Method that will return number

return number;

}

}

This is the class that edits and add the object

public class FindNum{

public static void main(String[] args){

Num example = new Num(5); //creates an object of the class Num and sets the int number to 5

example.setNumber(7); //set the new value to 7

System.out.print(example.getNumber()); //returns the value and prints it

}

}
