while (Again == true){

System.out.print("Input the trapezoid\'s upper base(cm):");
Upper = scan.nextDouble(); //The upper base of the trapezoid
System.out.print("\r\nInput the trapezoid\'s lower base(cm):");

Area = (Upper + Lower) /2 *Height; //The area of the trapezoid
System.out.println("\r\nThe area of the trapezoid is" + Area + "cm2");
System.out.print("Do you want to calculate another trapezoid\'s area?
Input Y or N.");
YN = scan.nextChar();
if (YN == 'N'){
Again = false;
}
}
}
}
