java string split
提问by Nawshad Farruque
What should I do if I want to split the characters of any string considering gaps and no gaps?
如果我想拆分任何字符串的字符时要考虑间隙和无间隙，该怎么办？
For example, if I have the string My Names JamesI want each character individually like this: M y n a m e setc.
例如，如果我有一个字符串，My Names James我希望每个字符都像这样：M y n a m e s等。

You mean this?
你是这个意思？
String sentence = "Hello World";
String[] words = sentence.split(" ");
Also if you would like to get the chars of the string you could do this:
另外，如果您想获取字符串的字符，您可以这样做：
char[] characters = sentence.toCharArray();
Now you just need a loop to iterate the characters and do whatever you want with them.
现在您只需要一个循环来迭代字符并使用它们做任何您想做的事情。
Here a link to the java API documentation there you can find information about the String class.

class MindFreak {
static String makeSpaced(String s) {
StringBuilder res = new StringBuilder();
for(int i = 0; i < s.length(); i++) {
char c = s.charAt(i);
if(!Character.isWhitespace(c)) {
res.append(c).append(" ");
}
}
return res.toString();
}
public static void main(String[] args) {
System.out.println(makeSpaced("My Names James"));
System.out.println(makeSpaced("Very Spaced"));
}
}
