<pre class= "java" abp= "655" name= "code" >/** * Display names based on caller ID * When the phone calls will automatically match the phone number to save the name in the telephone book, When the phone number matching will generally be based on the number of digits after the match, * because different network environment issued by the number may be different, for example, some regions display area code, some may not show area code. The subject requirements are as follows: * On the caller number after the N-bit match, n through the parameter read to obtain, output all the matching number of names, many personal name between the 1:int * parameter type, the possible value of 0,7,8,9, when 0 need to exact match the caller number, That is to say, the number in the phone book and the caller number must be the same. * Parameter 2: string, for the caller number * Match the name, the number match fails to display "unknown" (excluding quotes) * Sample input: 7 09282357 * Sample output: Jane Cora * Tip: * Phone number length will not be less than the length to match * telephone number if less than the length to match, to skip, do not compare * matches are matched from the back of the string, such as number 12345678, when the 7-bit match, only the next 7 digits, that is 2345678 * phone number is used as follows Data, written directly into the code: * Person persons[] = {New Person ("Jack", "13572105859"), New Person ("Tom", "008602989282356"), New Pe Rson ("Ada", "02989282356"), New Person ("Alice", "89282356"), New Person ("Carmen", "01089282356"), New person ("Franc Es "," 123 "), New Person (" Jane "," 89282357 "), New person (" Selina "," 18220191828 "), New Person (" Ellen "," 18220191828 ")
