containsBothDigits

Language/Type: Java method basics mod parameters return
Author: Marty Stepp (on 2010/12/28)

Write a method named containsBothDigits that accepts three integer parameters a, b, and c. Assume that a is a positive integer (greater than 0) and that b and c are single-digit numbers from 0 through 9 inclusive. Your method should return true if a contains both b and c among its digits, and false otherwise.

For example, the number 433407 contains 4, 3, 0, and 7 as its unique digits, so a call of containsBothDigits(433407, 7, 3) should return true. If b and c are the same number, your method should return true if that digit appears at least once among the digits; in other words, the same digit from a could match both b and c. So for example, a call of containsBothDigits(433407, 7, 7) should return true.

The following table shows several other calls to your method and their results:

Call Value Returned Reason
containsBothDigits(12345, 2, 5) true 12345 contains the digits 2 and 5
containsBothDigits(3004955, 3, 0) true 3004955 contains the digits 3 and 0
containsBothDigits(1650, 6, 6) true 12345 contains the digit 6
containsBothDigits(12345, 1, 7) false 12345 does not contain a digit 7
containsBothDigits(42, 4, 7) false 42 does not contain a digit 7
