Write a program that asks the user to enter an account number as a string. The account number consists of 8 characters and is divided as follows:  The first 2 characters are digits and represent the branch (00 for Beirut, 01 for Saida, 02 for Tripoli).  The remaining 6 characters represent the customer’s account number A valid account number consists of exactly 8 characters.

		for (int i = 0; i < array.length; i++) {
			if(array[0]!='0') {
				System.out.println("Invalid input:!!!First symbol must be 0.Try again");
			}else if(!(Character.isDigit(array[i]))) {
				System.out.println("Invalid input:!!!Symbols should be digits.Try again");
			}else if(array.length!=8) {
				System.out.println("Invalid input:!!!Symbols should be 8.Try again");
