The program is an illustration of loops.
Loops are used to perform iterative and repetitive operations.
The correct program where comments are used to explain each line is as follows:
public class MyProgram extends ConsoleProgram {
public void run() {
//This prompts the user for the number of times to repeat the message
echo(" ", readInt("Times to repeat: "));
}
private void echo(String lineOne, String lineTwo, int numTimes) {
//The following iteration is repeated numTimes times
for (int i = 0; i < numTimes; i++){
//This prints lineOne
System.out.println(lineOne);
//This prints lineTwo
System.out.println(lineTwo);
}
}
}
