FINRA Mid/Senior Java Developer interview questions

The interview was setup through a staffing agency. Initial phone screen was for 30 minutes and the interviewer covered all topics related J2EE project development. It was a little high level and he was making sure if I know some keywords and the technology used. F2F was for about 2 hours. All of them had questions written down either in their phones or on paper. They were completely prepared to interview in all topics Questions were on CoreJava 1. what is finally, finalize and finalize 2. Difference between ArrayList and LinkedList (asked twice) 3. Write a program to create a outOfMemoryException 4. Stringbuilder vs StringBuffer 5. There is a linkedList list; for(int i=0;i<list.size();i++){ list.remove(elementAt (i)); } What happens when this code is run ? Other Questions: 1. Design a parking lot with special instructions for Handicapped Drivers 2. How to find the phone numbers in 50,000 HTML pages. 3. You have to read content from thousands of web pages, how do you make the process faster ? 4. difference between SAX and DOM 5. What happens when you type a web page address in the address bar 6. Did you use Spring 7. How did you implement Spring in struts ? 8. SQl - SQL query for fetching records of employees that have more than 1 ph number in the phone numbers table . It has been a while since I coded SQL and I completely forgot.. I think this may be the question that failed me in the interview. I just wished the recruiter from the staffing agency had told me something about the outcome like I was lacking some skills or they needed more experienced person etc .. The whole interview process was positive except for the no-update from the recruiter.
