Please stop trying to program by accident. Your code looks like the glued-together parts of 3 different approaches to solving the issue. Try to read the documentation on the topic (JavaDoc is your friend!) and apply what you learned instead.
String result = String.format("Voter: %-10d Candidate: %-10d Booth: %-10d", e.voteNo, vote, boothId);
System.out.println(result);
For more information on String.format check its JavaDoc.
Edit: apparently I didn't get the memo that there's actually a PrintStream.format, so you can actually write it like this:
System.out.format("Voter: %-10d Candidate: %-10d Booth: %-10d", e.voteNo, vote, boothId);
