Append InputStream object to String object

Possible Duplicate: Read/convert an InputStream to a String I'm trying to append data from a InputStream object to a string as follows: byte[] buffer = new byte[8192]; InputStream stdout; String s = ""; while(IsMoreInputDataAvailable()) { int length = this.stdout.read(buffer); s += new String(this.buffer, 0, length, "ASCII"); Is there an easier way of doing this without us

Reading an inputStream all at once

This question already has an answer here: Read/convert an InputStream to a String 56 answers What about Apache Commons IOUtils.readLines()? Get the contents of an InputStream as a list of Strings, one entry per line, using the default character encoding of the platform. Or if you just want a single string use IOUtiles.toString(). Get the contents of an InputStream as a String using the

一次读取inputStream

这个问题在这里已经有了答案: 将InputStream读取/转换为字符串56个答案 那么Apache Commons IOUtils.readLines()呢? 获取InputStream的内容作为字符串列表,每行一个条目,使用平台的默认字符编码。 或者,如果您只想使用一个字符串,请使用IOUtiles.toString()。 使用平台的默认字符编码将InputStream的内容作为字符串获取。 [更新]根据关于这个在J2ME上可用的评论,我承认我错过了这个条件,但是IOUtils源代

regex for matching something if it is not preceded by something else

So with regex in java, I want to write a regex that will match if and only if the pattern is not preceded by certain characters. For example: String s = "foobar barbar beachbar crowbar bar "; I want to match if bar is not preceded by foo. So output would be: barbar beachbar crowbar bar I know this is probably a very simple question. I am trying to learn regex, but in the meantime I need so

正则表达式匹配的东西,如果它没有其他的东西

所以用java中的正则表达式,我想写一个匹配的正则表达式,当且仅当该模式没有被特定字符前缀时。 例如: String s = "foobar barbar beachbar crowbar bar "; 如果bar没有被foo前缀,我想匹配。 所以输出将是: barbar beachbar crowbar bar 我知道这可能是一个非常简单的问题。 我正在尝试学习正则表达式,但是现在我需要一些东西来工作。 你想要像这样使用negative lookbehind : w*(?<!foo)bar 其中(?<!x)意

Understanding Quantifiers

I was going through the Java Tutorial on Quantifiers. There is a difference mentioned among Differences Among Greedy, Reluctant, and Possessive Quantifiers. I am not able to understand what's the difference exactly. Explanation provided as follows: Enter your regex: .*foo // greedy quantifier Enter input string to search: xfooxxxxxxfoo I found the text "xfooxxxxxxfoo" starting at inde

理解量词

我正在通过量词的Java教程。 在贪心,不情愿和拥有量词的差异中有所不同。 我无法理解到底有什么区别。 说明如下: Enter your regex: .*foo // greedy quantifier Enter input string to search: xfooxxxxxxfoo I found the text "xfooxxxxxxfoo" starting at index 0 and ending at index 13. Enter your regex: .*?foo // reluctant quantifier Enter input string to search: xfooxxxxxxfoo I found the text "xfoo

Reluctant quantifier acting greedy

This question already has an answer here: My regex is matching too much. How do I make it stop? 4 answers {1} in regex is redundant since any element without specified quantifier needs to be found once. Also making it reluctant doesn't make sense since it doesn't describe range of possible repetitions (like {min,max} where adding ? would tell regex engine to make number of repetiti

不情愿量词贪婪

这个问题在这里已经有了答案: 我的正则表达式匹配得太多了。 我如何让它停止? 4个答案 在正则表达式中{1}是多余的,因为任何没有指定量词的元素都需要被找到一次。 也使它不情愿没有意义,因为它没有描述可能重复的范围(如{min,max} ,其中添加?会告诉regex引擎使该范围内的重复次数尽可能接近min )。 这里{n}描述了精确的重复次数,所以min = max = n 。 现在,您应该可以通过使.+ (括号内的内容)不愿意来解决

Regex quantifiers and character classes

There are examples and descriptions of regex quantifiers in Java Tutorial. Greedy - eats full string then back off by one character and try again Regex: .*foo // greedy String to search: xfooxxxxxxfoo Found "xfooxxxxxxfoo" Reluctant - start at the beginning then eat one character at a time Regex: .*?foo // reluctant quantifier String to search: xfooxxxxxxfoo Found "xfoo", "xxxxxxfoo" Pos

正则表达式量词和字符类

在Java Tutorial中有正则表达式量词的例子和描述。 贪婪 - 吃完整的字符串,然后退出一个字符,然后再试一次 Regex: .*foo // greedy String to search: xfooxxxxxxfoo Found "xfooxxxxxxfoo" 不情愿 - 从一开始就开始,然后一次吃一个角色 Regex: .*?foo // reluctant quantifier String to search: xfooxxxxxxfoo Found "xfoo", "xxxxxxfoo" 拥有 - 吃整个字符串尝试一次匹配 Regex: .*+foo // possessive quantifier

Using capturing groups with reluctant, greedy, and possessive quantifiers

I was practicing regular expressions of java in the tutorial of Oracle. In order to understand greedy, reluctant, and possessive quantifiers better, I created some examples. My question is how those quantifiers work while capturing groups. I didn't understand using quantifiers in that manner, for example, reluctant quantifier looks as if it doesn't work at all. Also, I searched a lot

用勉强,贪婪和占有量词捕捉群体

我在Oracle教程中练习java的正则表达式。 为了更好地理解贪婪,不情愿和占有量词,我创造了一些例子。 我的问题是这些量词在捕捉群体时如何工作。 我不明白以这种方式使用量词,例如,不情愿的量词看起来好像根本不起作用。 此外,我在互联网上搜索了很多,只看到像(。*?)这样的表达式。 为什么人们通常用这种语法使用量词,而不是像“(.foo)??”? 这是一个不情愿的例子: 输入你的正则表达式:(.foo)?? 输入要
