I'm trying to find a way to split a String into an array of String(s), and I need to split it whenever a white spice is encountered, example
我正在尝试找到一种方法，将一个字符串分割成一个字符串数组(s)，我需要在遇到一个白色的spice时将它拆分。
"hi i'm paul"
“嗨,我是保罗”
into"
为“
"hi" "i'm" "paul"
“嗨”“我”“保罗”
How do you represent white spaces in split() method using RegularExpression?
如何使用正则表达式在split()方法中表示空格?

You need a regular expression like "\\s+", which means: split whenever at least one whitespace is encountered. The full Java code is:
您需要一个像“\s+”这样的正则表达式，这意味着:只要遇到至少一个空格，就进行分割。完整的Java代码是:
try {
String[] splitArray = input.split("\\s+");
} catch (PatternSyntaxException ex) {
//
}

String[] result = "hi i'm paul".split("\\s+"); to split across one or more cases.
String[] result = "hi i'm paul".split("\ s+");把一个或多个案例分开。
Or you could take a look at Apache Common StringUtils. It has StringUtils.split(String str) method that splits string using white space as delimiter. It also has other useful utility methods
或者你可以看看Apache通用的StringUtils。stringutil的。split(String str)方法，它使用空格作为分隔符分隔字符串。它还有其他有用的实用方法
