Mencari luas dan keliling lingkaran :

package ele;
class circle{
private double jari;
private double pi;

public circle(){
jari = 0;
pi =3.14;
}

private double luasCircle(double r){
return pi*r*r;
}

private double keliling(double r){
return 2*pi*r;
}

public void setJari(double jari){
this.jari=jari;
}

public double getluas(){
return luasCircle(jari);
}

public double getkeliling(){
return keliling(jari);
}
public static void main(String args[]) {
circle c = new circle ();
c.setJari(7);
System.out.println("luas lingkaran = " + c.getluas());
System.out.println("keliling lingkaran = " + c.getkeliling());
}
}



OUTPUT :

luas lingkaran = 153.86
keliling lingkaran = 43.96
