contoh program pemanggilan field oleh object pada java

 Contoh Program :

Kelas Main :
public class Main{
public static void main(String[] args){
karnivora harimau = new karnivora(“harimau”,”mamalia”);
herbivora gajah = new herbivora(“gajah”,”mamalia”);
karnivora hiu = new karnivora(“hiu”,”mamalia”);
herbivora kambing = new herbivora(“kambing”,”mamalia”);
herbivora ayam = new herbivora(“ayam”,”aves”);
System.out.println(harimau.getDetails() );
System.out.println(gajah.getDetails() );
System.out.println(hiu.getDetails() );
System.out.println(kambing.getDetails() );
System.out.println(ayam.getDetails() );
}
}
Kelas Hewan :
public class hewan {
public String nama;
public String jenis;
public hewan (String n, String j) {
nama = n;
jenis = j ;
}
public String getDetails() {
return “Name : “+nama+, “Jenis : “+jenis ;
}
public void makan () {
}
}
Kelas Karnivora :
public class karnivora extends hewan {
public karnivora (String nama, String jenis) {
super (nama, jenis);
}
public String berburu () {
return “berburu” ;
}
}
Kelas Herbivora :
public class herbivora extends hewan {
public herbivora (String nama, String jenis) {
super (nama, jenis);
}
public String berkembangbiak() {
}
}

OUTPUT :
