Question

Trying a simple example where I am entering the data through the console and adding them to a List. But the values of the last name,age entered repeats itself in the List.

private List<User> getData() throws IOException{
    User user=new User();
    List<User> userList=new ArrayList<User>();
    BufferedReader reader=new BufferedReader(new InputStreamReader(System.in));
    for(int i=0;i<2;i++){
        System.out.println("Enter name,age:");
        String values=reader.readLine();
        String[] value=values.split(",");
        user.setName(value[0]);
        user.setAge(value[1]);
        userList.add(user);
    }
    return userList;

}

On printing the userList, its seems that the list is populated with final values I entered through the console.
Example,

Enter name,age: rickesh,22
Enter name,age: john,21

Contents of List: [john 22,john 22]

public class User { 
    private String age;
    private String name;

    public String getAge() {
        return age;
    }
    public void setAge(String age) {
        this.age = age;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

Create new User in a for loop.

private List<User> getData() throws IOException{    
List<User> userList=new ArrayList<User>();
BufferedReader reader=new BufferedReader(new InputStreamReader(System.in));
for(int i=0;i<2;i++){
    System.out.println("Enter name,age:");
    String values=reader.readLine();
    String[] value=values.split(",");
    User user=new User();
    user.setName(value[0]);
    user.setAge(value[1]);
    userList.add(user);
}
return userList;
}
