Question

If I have a class as follows

class Log {

    int rev;
    String auth;
    String date;
    List<PathInfo> pathinfolist;

    public LogProcess(int rev, String auth, String date,
            List<PathInfo> pathinfolist) {
        super();
        this.rev = rev;
        this.auth = auth;
        this.date = date;
        this.pathinfolist = pathinfolist;
    }

    public int getRev() {
        return rev;
    }

    public void setRev(int rev) {
        this.rev = rev;
    }

    public String getAuth() {
        return auth;
    }

    public void setAuth(String auth) {
        this.auth = auth;
    }

    public String getDate() {
        return date;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public List<PathInfo> getPathinfolist() {
        return pathinfolist;
    }

    public void setPathinfolist(List<PathInfo> pathinfolist) {
        this.pathinfolist = pathinfolist;
    }
}

I have a LinkedList<Log> called logobject. I have added almost a 1000 objects of Log to logobject using logobject.add().

Now how do I access/iterate these values of the data members from the linked list?

Answer 1

You can iterate over these by using an enhanced-for loop.

for(Log l : logObject) {
     // Process each object inside of logObject here.
}

I would also encourage you to type your LinkedList as List<Log> = new LinkedList<Log>(), so you don’t run into issues with retrieving elements from your LinkedList.
