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");
}
