How to make an invalid option cause you to re-enter an option? Java

I'm coding a voting system for school, and wondering how to make an invalid vote not count as one of 5 votes? As in, if a invalid vote is cast, 5 are still left to be made, not 4.

How can I do this with the else statement which prints out the invalid option code?


string Variable;

Variable = JOptionPane.showInputDialog(blah);

if(boolean) {
code
}

else if

else if

else { JOptionPane.showMessageDialog(null, "You have entered an invalid option. Your vote has not been counted.");

JOptionPane.showMessageDialog(null, "Please re-enter your vote.");

How do I make the last statement repeat the string variable without counting as a vote?

boolean validVote = true;
