How to write this LOGIN test case in selenium [JAVA]

The flow is as follows.

if success login --> go to main page --> next user login in array(e-mail datas) if fail login --> open error-pop-up ---> clear input ---> next user in array(e-mail datas)

JavaAndExcelRead is good working. This class has excel data. There are current and invalid users in excel file. Element is pop-up ok. PROBLEM -----> TASK= If element not be have do this if element be have do this. I can't do this task.
