同时使用和。 作为扫描器类中的定界符

Question

I have read all the already posted questions but was unable to understand the syntax I know we have to use | but I don't know how to. I have no idea of regex. So pls tell me the complete statement of the useDelimiter function of scanner class.

I was trying to separate a,bc,de, into abcde Using next() of scanner class

Answer 1

The argument passed to useDelimiter is a regular expression. So in this case, you can just use an expression like "[,.]" which matches either , or . .

Answer 2

You can read entire String using Scanner . Then you will have some like following

 String str="a,b.c,d.e,";

Now you can use replaceAll() method to get what you want.

 String str="a,b.c,d.e,";
 System.out.println(str.replaceAll(",|\\."," "));

Out put:

a b c d e
