Hello, i have a big string with lots of words in it and i want to find a way to split this string into separate words.This probably means that whenever the program finds a space it means that this is a new word and should make a new string for that one until it meets a space again.Particularly i want to ... |

Hi there, i need some help with a verification system that i'm trying to do at the moment. The scenario is as follows: A user can login by entering a string that either consists of a: 2 alphabets and 8 digits (AB12345678) (old format) b: 10 digits (1234567891) (new format) My problem is verifying the first situation.

This is for Eclipse 3.0; it might be a little different for a 3.1 stream build. On an Eclipse-wide basis, go to Window | Preferences | Java | Installed JREs. Make sure there's a 1.4 or later JDK on that list, and make sure that the appropriate checkbox is checked. Now go to Window | Preferences | Java | Compiler. Pick ... |

The argument to split() is a regular expression, not just a plain old string. "|" is a special character in Java regular expressions; it represents "or", as in "this or that". Just an "|" alone ought to be an error, I'd think, but apparently it isn't; it seems to mean "nothing or nothing" in this context, so you're getting your string ... |

Well that's interesting. The reason I thought this is because WSAD complains over the call the String.split(). I'm using WSAD 5.1.2. I assumed that it was using the 1.4.1 JDK. Maybe I should move this thread over to the IBM/WebSphere area??? Compiling the same code from a command line with Java 1.5 works great. Why wouldn't WSAD like it? |

My doubt is why do i get the length as 12 though the length of the string is 11,i see that there is no element at index 0 There are actually two things working here... The first is... you are using "nothing" as the split string -- or to be more specific, "nothing OR nothing" as the split string. This means ... |

Yes it does. The 1-argument split method links both to the 2-argument split method and Pattern. Moreover, the 2-argument split method not only links to Pattern, but to Pattern.compile in particular. On the first line there's a link to the regular expression summary. On that last page (part of Pattern), it is clearly mentioned that: a) [ is used with ] ... |

A necessary skill for any programmer to develop is to read errors well and think on those lines, in some cases assume probable causes and dwell in to troubleshooting. In this case the error is quite descriptive about the mistake you are making. Try to analyze the error message a bit harder. Try harder to figure out such errors by yourself.. ... |

First I would replace String[] sep_list = { " ", "\n","[","]","{","}","(",")"}; with Character[] sep_list = { ' ', '\n', '[', ']', '{', '}', '(', ')' }; or not Then look at java.util.regex.Pattern class, it has static method called quote(String) and it returns "A literal string replacement" Now you call it like Pattern.quote(sep_list[someIndex].toString()) and add it to your pattern. Strings in pattern ... |

I'd prefer the character class [\s\W]. \s means whitespace ([ \t\n\x0B\f\r]), whereas \W is a synonym for [^\w] and \w is a synonym for [a-zA-Z_0-9]. Of course you can't use * since then all empty strings between all characters will match as well; the regex will be [\s\W]+. And because \W implies \s, \W+ will suffice. Of course, once you start ... |
Hi Folks, In my code, I am attempting to split a String. The String I have to split is huge and so this method returns very very big array causing heap space problems.

You can start by posting the actual code, because your code compiles and runs just fine for me (well, after I dropped the "extends Applet" and changed the init() method into a static main method). You have one major bug in your code though. You should never use == for comparing Strings; use equals instead: public class Test { public static ... |

If you can split the name and email address which are seperated by "<"- You will get an array of 2 elements- Name and Email(with a ">" at the end, you would have to delete it).

The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array.

Matthew already said it - you have to escape it twice. A single backslash is "\\" in Java. That's what you had. But backslash is a special character for regular expressions as well. So you need to escape it in your regular expression as well. The regular expression then becomes \\ (two backslashes), but because you need to escape these two ... |

You indeed have to escape the meaning of that metacharacter with a backslash; so you get \* for your regular expression; sadly enough the Javac compiler also uses backslashes in its String literals and the above isn't a legal java escape sequence; the solution is simple (but a bit ugly though): escape the special meaning of the backslash by adding yet ... |
