Download the following classes into your java program directory: CharQueue.class and QueueException.class. Then copy/paste
the following program and compile and run it:
//the program demonstrates a stack used to store characters
public class ShowQueue {
public static void main(String [] args) {
// creating a new queue
CharQueue cq = new CharQueue();
// a variable to store stack characters
char c;
cq.enqueue('a');
cq.enqueue('b');
c = cq.dequeue();
System.out.println("c = " + c);
cq.enqueue('c');
cq.enqueue('d');
while( !cq.isEmpty()) {
c = cq.dequeue();
System.out.print(c);
}
System.out.println(); // new line
}
}
This is an example from CSci 2101 course.
