printing array

[mayhewj7]

how would you go about printing the contents of an array from a file one line at a time?

I want it to print like this:

Miami, Florida
Daytona Beach, Florida
San Francisco, California
etc....

Could anyone help me with this? thanks

array from a file? Do you mean that you read the file into an array (or possibly better, a collection) of String?

If so, wouldn't a for-loop seem like it would work well here?

[mayhewj7]

Would you have an example of that?

Which of the following:

• Print contents from a File?
• Print contents from an array?
• Pass contents from a file to an array and then print it?
• Pass contents form an array to a file and then print it?
• None of the above

Luck,

Here's something I found on how to read a file as a String. Works great for me:

private String readFileAsString(String filePath) throws IOException {
     StringBuilder fileData = new StringBuilder(1000);
     BufferedReader reader = new BufferedReader(
          new FileReader(filePath));
     char[] buf = new char[1024];
     int numRead = 0;
     while((numRead=reader.read(buf)) != -1){
          fileData.append(buf, 0, numRead);
     }
     fileData.trimToSize();
     reader.close();
     return fileData.toString();
}

That reads the entire file as a String.. Not each word as a String in an Array..
to get each word in array, you could do this:

ClassName cs = new ClassName();
String sample = cs.readFileAsString(sample.txt);
String[] sampleArray = sample.split(" ");

I think that would work. I'm not the greatest at regular expressions, someone correct my split() if I'm wrong. Then use the following syntax to print the array:

for(int i = 0; i < sampleArray's length; i increments) {
     print out sampleArray[i];
}

Hope that helped.
