Is there a way to add array objects to a class?

I am very new to this but I am trying to add object arrays to a class in android studio. I have created a "User" class that will be used to store information of each user. I need to create an object for each user, and set the appropriate variables (name, password and favourite color), and store this in a data structure. As you can see in the code below ive been trying to figure out the best way to go about this but I am still unsure. If anyone can please help or give me any guidance it would be muchly appreciated.

public class User {

String user1[] = new String[3];
String user2[] = new String[3];
String user3[] = new String[3];
String user4[] = new String[3];
String user5[] = new String[3];

String user[] = {"Jason", "Sword", "Red"};

}

I think you need to change your structure a bit.

The class you have given us above isn't really a User, but a group of Users. I suggest you rename the class accordingly, e.g. UserGroup. 'Users' would also work just fine, but if someone is skimming quickly through the code they might think they read 'User' instead and get muddled. I am pretty sure I would!

Go and make a different class called User, which has a bunch of String fields in it for the different values you want to store, e.g.

public class User {
  String name;
  String weapon;

  public User(String name, String weapon) {
    this.name = name;
    this.weapon = weapon;
  }

}

Back in your UserGroup class, don't hold String arrays but actual Users, e.g.

public class UserGroup {

  User user1 = new User("Jason", "Sword");

}

As you are using Android Studio, I suppose that you wanna make an app. So if that's the idea you must store user data in files because class is a logical construct. class works only at runtime. So when you use a class, after runtime it will destroy the user data which is practically of no use. It's better to use files and Objects and don't forget to use Secure Hash Algorithms for password.

You can use two Hash Map.
'UserAPass' is used to store name and password.
'UserAFavCol' is used to store name and favorite color.
Put both hash maps as static so that it can be shared among instances as per app usage.

import java.util.HashMap;
public class User {
static HashMap<String, String> UserAPass = new HashMap<String, String>();
static HashMap<String, String> UserAFavCol = new HashMap<String, String>();
    void addUser(String name, String pass, String col) {
        UserAPass.put(name, pass);
        UserAFavCol.put(name, col);
    }
}

public class User {
public User(String name, String password, String favouriteColor) {
    this.name = name;
    this.password = password;
    this.favouriteColor = favouriteColor;
}

private String name;

private String password;

private String favouriteColor;

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getFavouriteColor() {
    return favouriteColor;
}

public void setFavouriteColor(String favouriteColor) {
    this.favouriteColor = favouriteColor;
}

public static void main(String[] args) {
    User users[] = {new User("Jason", "Sword", "red"), new User("Jack", "MyWord", "green")};
}

}
