[FIXED] How to print the output of an accessor of every instance of a class?

Issue

How would you go about creating a class like this:

public class tmUser {
    
    private String Username;
    private int wHours;
    static int numUsers;
    
    
    public tmUser(){
        Username = "";
        wHours = 0;
    }
    
    public tmUser(String U, int H){
        Username = U;
        wHours = H;
    }
    
    public void setUsername(String U){
        Username = U;
    }
    
    public void setwHours(int H){
        wHours = H;
    }
    
    public String getUsername(){
        return Username;
    }
    
    public int getwHours(){
        return wHours;
    }
    
    public static void initnumUsers(){
        numUsers = 0;
    }
    
    public static int getnumUsers(){
        return numUsers;
    }
}

and then printing all of tmUser instances Username variable? in maybe a for each loop? I'm hoping for something like:

for each(tmUser){
    System.out.println(Username);
}

This is for a menu in a program which displays all created users usernames.

Solution

You almost had it:

List<TmUser> tmUsers = ... 
for(TmUser user : tmUsers) {
    System.out.println(user.getUsername());
}

You would also want to capitalize tmUser into TmUser.
