Encapsulation Example:

public class Box
private int length;
private int width;
private int height;

public void setLength(int p)
{length = p;}

public void setWidth(int p)
{width = p;}

public void setHeight(int p)
{height = p;}

public int displayVolume()

public static void main(String args [ ])
Box b1=new Box(3,4,5);


Abstraction Example:

public class Animal
double energyReserves;

boolean isHungry() {
return energyReserves < 2.5;
void eat(Food f) {
energyReserves += f.getCalories();
public static void main(String[] args)
thePig = new Animal();
theCow = new Animal();
if (thePig.isHungry()) {
if (theCow.isHungry()) {
/*In the above example, the class Animal is an abstraction used in place of an actual animal.*/

Inheritance Example
