Hi.
I have a feeling I'm going to need help at every turn while I'm learning Java.
For some reason, when using the console, when I move the cursor, anything I type just overtypes text to the right of it. Is there any way I can change that please?
Also, I'm unable to copy and paste despite using Ctrl C and Ctrl V.
As for my code, I'm getting more error messages.
Example.java:
import java.util.Date;
import com.teamtreehouse.Treet;
public class Example {
public static void main(String []args) {
Treet treet = new Treet(
"craigsdennis",
"Feeling overwhelmed by learning to #code?" +
"Try out this thought hack I whipped up: http://buff.ly/1LjAZrJ #development #webdev",
new Date(1437084178)
);
System.out.printf("This is a new Treet: %s %n", treet);
System.out.println("The words are:");
for (String word: treet.getWords()) {
System.out.println("word");
}
}
}
Treet.java:
package com.teamtreehouse;
import java.util.Date;
public class Treet {
private String mAuthor;
private String mDescription;
private Date mCreationDate;
public Treet(String author, String description, Date creationDate) {
mAuthor = author;
mDescription = description;
mCreationDate = creationDate;
}
@Override
public String toString() {
return "Treet: \"" + mDescription + "\" - @" + mAuthor;
}
public String getAuthor() {
return mAuthor;
}
public String getDescription() {
return mDescription;
}
public Date getCreationDate() {
return mCreationDate;
}
public String[] getWords {
return mDescription.toLowerCase().split("[^\\w#@']+");
}
}

Thanks in advance for any help.

Courses Plus Student 7,254 PointsHi Sean,
It does look like Dmitriy helped you with your "word" problem. You should not be using quotes around the word.. "world". When you use quotes, it uses the String "word" and not the variable word.
I'll change his comment to an answer in case you feel it is sufficient to give a "best answer" to him.

1,925 PointsHi, Sean. Not sure I can tell you something reasonable about command line operations, but here are couple of things I noticed about code.
— you need to add trailing parenthesis right after method declaration in Treet class, so, getWords -> getWords() — change "word" to word inside for loop to print not just a literal, but actual value :-)

1,925 PointsGlad to hear that, Sean!
Yes, Jon is right, you need to remove quotes from "word"
for (String word: treet.getWords()) { // System.out.println("word"); "word" ---> word System.out.println(word); }

33,235 PointsHi Dmitriy. I've just added a pair of parentheses in that line and now it's working. It's saying "word" down the left of the console. Thanks. :-)
