Adding 3 string into 3 variable

Question

My Account class have 3 variable to store name, id and password

and my method addAcount() get 3 parameter and pass all into the 3 variable.

The problem is i cant pass the 3 parameter item into the 3 variable.

my 3 variable declaration :

private String[] id = new String[100];
private String[] pass = new String[100];
private String[] name = new String[100];

here's my method:

public void addAccount(String id, String pass, String name){
        for(int i=0; i < this.id.length;i++){
            if(this.id[i]==null){
                this.id[i]=id;
                    for(int a = 0; a <this.pass.length;a++){
                        if(this.pass[a]==null){
                            this.pass[a]=pass;
                                for(int b=0;b<this.name.length;b++){
                                    if(this.name[b]==null){
                                        this.name[b]=name;
                                            break;
                                    }
                                }
                        }
                    }
            }
    }

Any Help will be Appreciated

I means i need to add single id, single pass and single name to the variable but not adding the whole array, sry for my bad english — Kai Loon, Oct 15 '15 at 09:34
you could just hold an `int index = 0` variable which you increment each time after calling `addAccount` this way you can assign them directly — SomeJavaGuy, Oct 15 '15 at 09:34

To access all elements Your method header shoud be :-

public void addAccount(String[] id, String[] pass, String[] name){
 //your code here
 // By looping over array you can get the strings in it
  for(int i = 0 ; i < id.length ; i++){
    String str_id = id[i];
  }
}

And to call it :-

addAccount(id,pass,name);

To access specific string at specific position :-

String str_pass = pass[5];//by his you will get the 6th element(zero base indexing )

But be aware if you direct access the array if the index you use greater than array.length you will get array out of boundary exception

In this situation you can use this:

public void addAccount(String id, String pass, String name)
        {     
          //These for loops look up the first empty spot in the array and
          //insert the chosen parameter in that spot once

            //Add ID to array
            for (int i = 0; i < this.id.length; i++)
            {
                if (this.id[i] == null)
                {
                    this.id[i] = id;
                    i = this.id.length;
                }
            }
            //Add Pass to array
            for (int a = 0; a < this.pass.length; a++)
            {
                if (this.pass[a] == null)
                {
                    this.pass[a] = pass;
                    a = this.pass.length;
                }
            }
            // Add name to array
            for (int b = 0; b < this.name.length; b++)
            {
                if (this.name[b] == null)
                {
                    this.name[b] = name;
                    b = this.name.length;
                }
            }
        }

Edit: changed the code so the array length won't matter
