[1.8] Copying Characters From a String

[CritiqualError]

[i am using Eclipse and Forge 1.8]

 

I was wondering how to take certain characters from a string.

Example:

I convert the number 123456 to a string then I want to assign every 2 characters to a variable: a="12" b="34" c="56".

Like that. How would I go about doing that?

 

Or maybe have it start from the end, so it can be like, 12345678 and end up like: a="1234" b="56" c="78". only splitting them between those 3 groups, the a group allowed to overflow as much as it wants.

strings go in "12345" numbers like 12345

strings go in "12345" numbers like 12345

 

Did you even read it?

its called converting an integer to a string.

Thanks a bunch. It is very nice to know that I can rely on the forums when I'm stuck on a problem. Such a swift response.

I also now know new coding (i coded a bit in other programs so I kinda get how coding works, just this minecraft stuff is rather new to me) I will put this to good use and see what I can do.

 

First let's create a splitter (from the Guava library) with the characteristics we want:

static Splitter splitter = Splitter.fixedLength(2).limit(3);

 

For your first problem:

 

List<String> split = splitter.splitToList("12345678"); // returns [12, 34, 5678]

 

For the 2nd one:

List<String> split = Lists.reverse(Lists.newArrayList(splitter.split(StringUtils.reverse("12345678")))); // StringUtils is from Apache Commons Lang
split.replaceAll(StringUtils::reverse); // returns [1234, 56, 78]

 

Both libraries mentioned above are shipped with Minecraft.
