Question

I have an array which store some data inside it. Inside the array there will be some data like this

Alluser[0] = John || 20 || Student;

Alluser[1] = Will || 19 || Student;

I wanted to split the data and arrange one user into one array. Something like this

 user0[0] = John;
 user0[1] = 20;
 user0[2] = Student;

The number of user will constantly increase later on. But I don’t know how to constantly create new array for new user.
I tried something like this

for(int i=0;i<Alluser.length;i++){
      String[] user[i]= Alluser[i].split("||");
}

I knew that String[] user[i] is wrong, I just don’t really the structure of the correct way of handling this issue. Any comment and answer will be highly appreciated.

Use OOP:

Create a class User and store List<User> listOfUsers;

In this case you’ll have a list of users and get access to each item, delete it or add new users.

class User{
    String name;
    int age;
    ...
}

and also you can iterate:

for (User eachUser: listOfUsers){
    eachUser.getName();
}
...
