I am quite new at JAVA however, I tried what you posted and it works for me - trying using this code

class Example{

public static void main(String [] args){

double gallons;

double liters;

int counter;

counter = 0;

for (gallons = 1; gallons <=20; gallons++){

liters = gallons * 3.75;

System.out.println("We have " + liters + " liters");

counter++;

if (counter == 5){

System.out.println();

counter = 0;

}

}

}

}

class Example{

public static void main(String [] args){

double gallons;

double liters;

int counter;

counter = 0;

for (gallons = 1; gallons <=20; gallons++){

liters = gallons * 3.75;

System.out.println("We have " + liters + " liters");

counter++;

if (counter == 5){

System.out.println();

counter = 0;

}

}

}

}

This is a common error. We even have a FAQ on it.

There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
