I am currently trying to make use of the java string function someString.replaceAll() to find commonly used words (and, the, by, of, etc) and replace them with " ". Based on the answers to the question at Whitespace Matching Regex - Java, I produced this function call:
data.replaceAll("(?i)\\sthe\\s", " ")
However, it isnt working and I'm really not sure why. Nothing about it looks wrong based on what I've found. Please help me!
Strings are immutable!
data = data.replaceAll("(?i)\\sthe\\s", " ");

Any ideas how to effeciently convert the String "TDMaturityReinvestOnNotSelected" to "TD Maturity Reinvest On Not Selected" using a java function?
Cheers

This brilliant answer to RegEx to split camelCase or TitleCase (advanced) should work nicely.
Below is an excerpt from that answer:
final String pattern = "(?<!(^|[A-Z]))(?=[A-Z])|(?<!^)(?=[A-Z][a-z])";
for (String w : "TDMaturityReinvestOnNotSelected".split(pattern))
{
System.out.println(w);
}
And the ouput to show it running:
Edit: You'll need to reassemble the split words with spaces, but that should be trivial to work out.

I want to detect the file structure in a string.
e.g
if I have a string as /name/test/testme/2 I should be able to store it in a arraylist as different elements like {[name],[test],[testme],[2]}
String[] elements = "/name/test/testme/2".split("/");
More info can be found in the String.split() Javadoc
As Lukas pointed out, (please give him some upvoting) you should use the split method.
String[] elements = "/name/test/testme/2".split("/");
The regular expressions are not used to split strings in sections. Regular expressions are used for matching the target string with a specific generic format. In this case a boolean value indicating if the strings match is returned.
Hope I helped!

Given a string "Hello". I only want all the letters after the first letter to be in my new string.
E.g.: "ello"
How could this be done?
Tried pattern matching but cant get it to work :(
Try this:
String s = "Hello";
String newS = s.substring(1); // newS is "ello"
The above will create a new string containing all the characters of the original, except the first one. See the documentation for more details.

How to insert multiple tabs string in Java?
This example:
getName() + '\t' + '\t' + getLastName(), does not work.
Your example should work; however there's no reason to append each tab character individually. This works, too:
getName() + "\t\t" + getLastName();
The errors you are getting are not related to the tab characters.
Your syntax is screwy. Try this.
String whatever0 = "firstname"+"\t"+"\t"+"lastname";
String whatever1 = "firstname"+"\t"+"\t"+"\t"+"lastname";
System.out.println(whatever0);
System.out.println(whatever1);
You'll see that they give different results.

Can you use strings in some way to define the source and target of files.move.
Heres the documentation http://docs.oracle.com/javase/tutorial/essential/io/move.html
According to the javadoc, you can not use strings as arguments for Files.move .
What seems to be a better solution for you, is using the rename method on File. Something like this:
File file = new File("/path/to/file/to/be/moved");
boolean moved = file.renameTo("/new/path/for/the/file");
if(!moved)
//Handle the error
Short answer is no: Files.move requires Path objects. That said, you can use Paths.get(str) to simply turn a String into a Path.
