Java String split方法被2个或更多空格分隔

Question

How can I split a string by "2 or more spaces" only using the java split method

An example:

"cat dog    horse   elephant"

will be splitted into:

cat dog
horse
elephant

Thanks.

Answer 1

You need to split the String using following regex

\\s{2,}

This will split the string by 2 or more spaces

String str = "cat dog    horse   elephant";
String[] parts = str.split("\\s{2,}");
