java - Sorting Strings in an Array by Char -


i'm trying sort list of strings in array alphabetical order without using sort method. 

public static string[] sortedadjectives(string[] original) {     string[] sortedarray;     int avalue = 65;     string word = "";     sortedarray = new string[25];     for(int = 0; <25; i++)     {         original[i]=word;         char c = word.charat(0);         sortedarray[c-avalue]=word;      }     return sortedarray;

is method, and

public static void main(string[] args) throws filenotfoundexception {         scanner names = new scanner(new file("names.txt"));         scanner adjectives = new scanner(new file("adjectives.txt"));         string[] adjectivearray;         adjectivearray = new string[25];         int counter = 0;         while (counter<25)         {             string in = adjectives.next();             fixcapitalization(in); //method fixes capitalization             adjectivearray[counter]=in;             counter++;         }         sortedadjectives(adjectivearray);

is put items file array. i'm getting 

exception in thread "main" java.lang.stringindexoutofboundsexception: string index out of range: 0     @ java.lang.string.charat(unknown source)     @ hmwk.sortedadjectives(hmwk.java:56)     @ hmwk.main(hmwk.java:24)

when try run program , can't figure out i'm going wrong. if point me in right direction i'd appreciative. time.

you have word initialized empty string:

string word = "";

then calling charat(0) on empty string. can't that. string needs @ least longer 1 character in order call method.
