How To Use Access Specifier in Java Programming Language

The Following script is the simplest way to declaring and using Access Specifier in Java programming language:

Class diagram:

Java program:

class Titik{ //titik = point = dot

 private int X;

 private int Y;

 protected void setX(int X){

  this.X = X;

 }

 public int getX(){

  return X;

 }

 protected void setY(int Y){

  this.Y = Y;

 }

 public int getY(){

  return Y;

 }

}

class Titik3D extends Titik{ //titik3D = 3Dpoint

 private int Z;

 protected void setZ(int Z){

  this.Z = Z;

 }

 public int getZ(){

  return Z;

 } 

}

class AccessSpecifier{

 public static void main(String args[]){

  Titik T2D = new Titik();

  Titik3D T3D = new Titik3D();

  T2D.setX(10);

  T2D.setY(20);

  System.out.println("Titik 2D ("+ T2D.getX() +","+ T2D.getY() +")");

  T3D.setX(10);

  T3D.setY(20);

  T3D.setX(30);

  System.out.println("Titik 3D ("+ T3D.getX() +","+ T3D.getY() +","+ T3D.getZ() +")");

 }

}
