Question

1- Write a Java program called ArabicMonth that randomly generates an integer between 1 and 12 and displays the month name Jan, Feb, …, December for

the number 1, 2, …, 12, accordingly..

Sample Run:

9 Oct

2- Write a program that prompts the user to enter the exchange rate from currency in U.S. dollars to Saudi Riyals. Prompt the user to enter 0 to convert from U.S. dollars to Saudi Riyals and 1 to convert from Saudi Riyal and U.S. dollars. Prompt the user to enter the amount in U.S. dollars or Saudi Riyal to convert it to Saudi Riyal or U.S. dollars, respectively.

Here are the sample runs:

Enter the exchange rate from dollars to SR: 3.75

Enter 0 to convert dollars to SR and 1 vice versa: 0

Enter the dollar amount: 100

$100.0 is 375.0 SR
