java中字符串数组更换某些字符串 [英] java replace certain string in array of strings

问题描述

让我们说我有在Java这个字符串数组

let's say I have this string array in java

String[] test={"hahaha lol","jeng jeng jeng","stack overflow"}

但现在我想以取代在数组中字符串的所有空格以上20％，使它像这样

but now I want to replace all the whitespaces in the strings inside the array above to %20, to make it like this

String[] test={"hahaha%20lol","jeng%20jeng%20jeng","stack%20overflow"}

我该怎么办呢？

推荐答案

遍历数组，并取代每个条目的EN codeD版本。

Iterate over the Array and replace each entry with its encoded version.

像这样，假设你实际上是在寻找URL兼容的字符串只：

Like so, assuming that you are actually looking for URL-compatible Strings only:

for (int index =0; index < test.length; index++){
  test[index] = URLEncoder.encode(test[index], "UTF-8");
}

要符合当前的Java，你必须指定的编码 - 但是，它应该永远是 UTF-8

To conform to current Java, you have to specify the encoding - however, it should always be UTF-8.

如果你想要一个更宽泛的版本，做什么其他人建议：

If you want a more generic version, do what everyone else suggests:

for (int index =0; index < test.length; index++){
    test[index] = test[index].replace(" ", "%20");
}
