Regeln gelesen und beachtet.
Hier mein Code vorab
Java:
public class Masterkey{
String password;
int length;
public Masterkey(String password, int length) {
this.password = password;
this.length = length;
}
public int getLength() {
return length;
}
public void setLength(int length) {
this.length = length;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Java:
public class Data{
String website;
String username;
String password;
public Data(String website, String username, String password) {
this.website = website;
this.username = username;
this.password = password;
}
public String getWebsite() {
return website;
}
public void setWebsite(String website) {
this.website = website;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Java:
import java.util.ArrayList;
public class PasswordManagement{
private ArrayList<Data> data;
private ArrayList<Masterkey> masterkey;
public PasswordManagement() {
data = new ArrayList<Data>();
masterkey = new ArrayList<Masterkey>();
}
//Methodes for adding
public void addUser(String website, String username, String password){
data.add(new Data(website, username, password));
}
public void addMasterkey(String password, int length){
masterkey.add(new Masterkey(password, length));
}
//Methode for showing the values
public String showData(){
String s = "ID\t\t\tWebsite\t\t\tUsername\t\t\tPassword";
for(Data u : data){
s = s + "\n" + data.indexOf(u)+ "\t\t\t" + u.getWebsite() + "\t\t\t" + u.getUsername() + "\t\t\t" + u.getPassword();
}
return s;
}
//Methodes for searching after values
public Data sucheUsername(String username){
for(Data a : data){
if(username.equals(a.getUsername())){
return a;
}
}
return null;
}
public Data sucheWebsite(String website){
for(Data a : data){
if(website.equals(a.getWebsite())){
return a;
}
}
return null;
}
//Methode for getting the index
public int getIndexByUsername(String username)
{
for(Data a : data)
{
if(a.getUsername().equals(username))
return data.indexOf(a);
}
return -1;
}
//Methode for removing the selected index
public void removeData(int index){
data.remove(index);
}
// Methodes for updating the selected values
private void updateMasterkey(int index,Masterkey password) {
masterkey.set(index, password);
}
private void updateUsername(int index, Data username){
data.set(index, username);
}
private void updateWebsite(int index, Data website){
data.set(index, website);
}
private void updatePassword(int index, Data password){
data.set(index, password);
}
}

}
}Probleme (bekannte)
1. "update" (unter PasswordmanagementUI und Passwordmanagement) funktioniert nicht.
2. Speicherung und Lesen von einer "output" Datei fehlt. (BufferedReader versucht.. aber dann stimmt die Formatierung nicht)
Würde mich über Tipps freuen und wäre auch super dankbar
Ich programmiere erst seit kurzem (merkt man wohl *hust*) will mich nur auf die Ausbildung vorbereiten. Habe bereits "Java ist auch eine Insel" sowie "Programmieren lernen mit Java" gelesen... nur blicke ich nicht durch sobald ich selbst programmiere
