help! how to use Scanner to put items into an array

Heather189 — GMT

So, the assignment is to read from an input file, and store each word into an array. Please look at my code and tell me what you think is wrong. btw I'm totally unfamiliar with the Scanner class. I keep getting an error message:

if(inputFromFile != null){
while (inputFromFile.hasNextLine()) {
String line = inputFromFile.next();

for (int i = 0; i < array.length; i++)
array[i] = line;
}
}

for (int i = 0; i < array.length; i++)
System.out.println (array[i]);

It's just not printing what I want it to print. Help me!

I'm not sure that I'm following your logic, specifically the first "for" loop. You'll want to keep track of where you are in the array but your first loop just sets the same variable to each array element. Additionally, you'll want to use "hasNext" since you're parsing tokens, not lines. Something more like:

[code]
String[] array = new String[100]; // this can only hold 100 Strings at most

int arrayIndex = 0;
if(inputFromFile != null){
while (inputFromFile.hasNext()) {
String line = inputFromFile.next();

if( arrayIndex < array.length )
array[arrayIndex++] = line;
else
System.out.println( "there are too many words for this program" );
}
}

for (int i = 0; i < arrayIndex - 1; i++)
System.out.println (array[i]);
[/code]
