如何在Java中使用/和空格分割字符串

Question

My problem is I have a string like this

String text="UWU/CST/13/0032 F"

I want this to split by / and white spaces and put into a array.So finally the array indexes should include following UWU, CST, 13, 0032, F

Answer 1

text.split("[/ ]")或text.split("[/ ]", -1)如果要返回尾随的空标记。

Answer 2

Use the string.split(separator) method that takes a String (regex expression) as an argument. Here is the documentation. http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#split(java.lang.String)

If you have:

String text = "UWU/CST/13/0032 F";

You can separate it by the white space first, splitting it into an array of two Strings, and then split the first String in the array by "/".

    String text = "UWU/CST/13/0032 F";

    String[] array = text.split(" ");
    String[] other = array[0].split("/");

    for (String e : array) System.out.println(e);
    for (String e : other) System.out.println(e);

This code outputs:

UWU/CST/13/0032
F
UWU
CST
13
0032

Regular expressions can be used in Java to split Strings using the String.split(String) method.

For you particular situation, you should split the string on the regular expression "(\\s|/)" . \\s matches white space while / literally matches a forward slash.

The final code for this would be:

String[] splitString = text.split("(\\s|/)");
