如何在Java中使用split函数拆分像p ^ q这样的字符串？

Question

I want to split a string like "p^q" into two strings, ie "p" and "q". How can I do this using "string.split" in Java. I have used syntaxes like s.split("^") , s.split("\\^") , and s.split("\\\\^") ! But the arraylist always has one element! Thanks

Answer 1

System.out.println(Arrays.toString("p^q".split("\\^")));

prints

[p, q]

which proves that the array returned by split has not one, but two elements, and exactly those that you require.
