Split Numbers 1234 into 12 & 34

in Core Library Questions • 2 years ago

I need to split four consecutive numbers into two numbers (proHTML drops punctuation from data Im scraping, the original data is in format 12.34). Slit, SplitTokens, & Trim require some token or space to work with. I thought I might be able to convert the string into list and then use subset to extract the two numbers. Is there a processing.org programmatic equivalent to rtrim or ltrim?

When I try methods to use subset, I'm getting cannot convert string[] to string errors. Any suggestions?

tempstring = htmlList.pageList.get(i+1).toString(); // store the next record into tempstring.
String[] p = new String[1];
p[0] = tempstring;
String p1 = subset(p,0,1); String p2 = subset(p,1,3);
pressure = p1 + "." + p2;

subset() is an array function, not a string function. If you look at the reference, under String entry, you will find a number of useful methods, including substring().

thanks .. I'll take a look at subset() its probably what I'm looking for .. I wonder why subset() is not listed in the reference docs that came with processing.org Help | Reference.

That's substring(), not subset().
And it is there, as I point out, under the String entry: this method isn't a function (in the sense of subset() or rect()), but is used in the context of a string (as someString.substring(5) for example).
