Java从字符串中选择单词 [英] Java selecting words from a string

问题描述

大家好。对于这个令人尴尬的新手问题，我很抱歉，但我似乎无法弄明白这个命令。我对python很好，并且在jython中有一个脚本，我正在转向纯java（并沿途学习）。

HI Everyone. I'm sorry for this embarrassingly newbie question but I cannot seem to figure out the command to do it. I'm okay with python and had a script in jython that I'm convering to pure java(and learning along the way).

我有一个字符串： Java真的很酷

我知道如何去除字符串以获得最终结果：真的很酷

I know how to strip the string to get the final result: really cool

但我不确定在java中执行此操作的命令。我发现java中的命令是专门通过文本来完成的，但我想使用空格作为分隔符并获取单词。

but i'm not sure the command to do it in java. I found commands in java to do it specifically by text but I want to use a space as a deliminator and get the words.

有人可以告诉我使用什么java命令？我希望能够删除前两个单词和/或专门选择我想要的单词。

Can someone tell me what java command to use? I would want to be able either remove the first two words and/or specifically select the words I want.

谢谢，

推荐答案

我认为您正在寻找 String.split 。

I think you are looking for String.split.

String s = "Java is really cool";
String words[] = s.split(" ");
String firstTwo = words[0] + "  " + words[1]; // first two words
String lastTwo = words[words.length - 2] + " "
        + words[words.length - 1]; // last two words
