Using an if-else statement to at any point make the program end

I am creating a simple program that takes some input and turns it into an output to .txt file.

I have been trying to use if-else statements to make it so that after it has received a name ;

    //user enters name and then moves to next line
    System.out.println("Enter Your Name");
    gamerName = Scan.nextLine();

it will either move onto the next part (if a name is entered) or break. How and where will i properly add and format these if-else statements? thanks you

            //variables 
        int[] minutesPlayed = new int [100];
        String gamerName, gamerReport;

        //formatting for output and input
