}
System.out.println("Total dinar required is:");
System.out.println("Category Amount(Dinar)");
Iterator x = set1.descendingIterator();

}
System.out.println("Total amount needed in Dinar:"+ tamount);
System.out.println("Total amount needed in Rupees:"+ tamount*18.565);
}
}
Output should be like :
Enter item
Fried Rice
Enter amount(Dinar)
20
Do you want to continue(yes/no):
yes
Enter item
Chicken Lollipop
Enter amount(Dinar)
25
Do you want to continue(yes/no):
yes
Enter item
Coffee
Enter amount(Dinar)
5
Do you want to continue(yes/no):
no
Total dinar required is:
Item Amount(Dinar)
Chicken Lollipop25
Fried Rice 20
Coffee 5
Total amount needed in Dinar: 50
Total amount needed in Rupees: 928.25
IF I USE nextLine(); some inputs are SKIPPED !!
