在字符串中找到某个字符后，Java插入空格

Question

How would I go about adding a space AFTER a specific character in the string has been found? Example.... I'd want to add a space after the "#" character in that string. I'm also wondering how I could get the position I was currently at if there were multiple "#" in my string.

(2/9) B (4/3) / # (1/2) (-1/3) (3/2) (-1/11) * * - (1/2) + (2/2)

你可以做

str = str.replace("#", "# ");
