Hi im trying to write a program that sorts an array in alphabetical order and then into phone book order,
Eg input:
Jane Pascal 364756
Bob Smith 364758
Joe Bloggs 253647
The output should be:
Bloggs, Joe 253647
Pascal, Jane 364756
Smith, Bob 364758
The plan is to have each name (forename + surname) in different array's and the numbers in another and not sure how to sort them as above, any help would be great.
Jump to PostAn even better way to do this would be to create a Person class with the appropriate fields, and create a new class that implements Comparator for each desired sort order. See here.
I would use the StringTokenizer to parse up the individual strings according to the spaces;
String foreName, surName, number;
StringTokenizer st = new StringTokenizer(str);
foreName = st.nextToken;
surName = st.nextToken;
number = st.nextToken;then rearranging the strings
newStr = surName+", "+foreName+" "+number;stick those into an array and then use the Arrays.sort
java.util.arrays.sort(stringArray);Thanks, I new there was an Array.sort method just wasnt sure how to use it, cheers!
