}
public void info(){
System.out.println("Nama = "+this.Nama);
System.out.println("Alamat = "+this.Alamat);
System.out.println("Umur = "+this.Umur);
}
public static void main(String args[]){
Scanner masuk = new Scanner(System.in);
System.out.print("Masukkan Nama: ");
String nm = masuk.nextLine();
System.out.print("Masukkan Alamat: ");
String alamat = masuk.nextLine();
System.out.print("Masukkan Umur: ");
int Umur = masuk.nextInt();
Person oop = new Person(nm,alamat,Umur);
oop.info();
}
