Saving

My question was this!

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = { 0x90, 0xA2, 0xDA, 0x0F, 0x50, 0x35 };

IPAddress arduino(192,168,0,12);
IPAddress server(192,168,0,15);

EthernetClient client;

String username[] = {"Admin","Skut","Arbek","Kubda"};
String password[] = {"12344","stra","124ssgra","!#¤%"};

void setup() {
Serial.begin(9600);
Ethernet.begin(mac,arduino);
Serial.println("Connecting...");
if (client.connect(server, 8888)){
Serial.println("Connected to Server");
} else {
Serial.println("Connecting failed");
}
}

boolean verify(){
for(int i = 0; i < 4 ; i++){
if((username == "Admein") && (password == "12344")){
* return true;*
* }*
* }*
* return false;*
}
void loop(){
* if (client.available()){*
* char c[2];*
* for(int i = 0; i < 2 ; i++){*
_ c = client.read();
* Serial.print(c[1]);
//Serial.print(c[2]);
}
}*_

if (!client.connected()){
* Serial.println();*
* client.stop();*

* while(true);*
}
}
The question is! How can you save a username and a password sent from the server in two different variables o the arduino?
