Search an of objects for a string

Question

I have an array which contains phone objects..each object contains lastname, firstname, address and telnumber.
eg array called entry has values
entry[2] = ('smith', 'paul' , '44 test st' , '123456)
and so on for each cell in the array.
How do I write code to search the array by lastname, where lastname to look for = 'doyle'....
can this be repeated for each item that the object contains, i.e. by firstname, address and telnumber too?
Thoughts and comments are appreciated.

Answer 1

Firstly...make sure you use dynamic growing Array
try this sample code
entry[] = {"smith", "paul" , "44 test st" , "123456"}
Map map = new HashMap();
map.put("firstName","smith");
map.put("lastName","paul");
map.put("add","44..");
map.put("telno","123456");
System.out.print(map.get("telno"));
