ArrayStack<String> stk1=new ArrayStack<String>();
String weekName[ ] = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"};
String strB = (String)stk1.top();
String strA = (String)q1.peekFront();
while(strA != strB){
stk1.pop();
q1.dequeue();
strB=(String)stk1.top();
strA=(String)q1.peekFront();
}
System.out.println("strA= " + strA);

After executing the loop, strA contains the following day :
