Why won't this strip out the '$''s
getplarray[i].replaceAll("$","")

(I'm assuming you're working with a String.)
Notice in the API that replaceAll treats the first String argument as a Regular Expression. In that context, the '$' character has special meaning to represent the end of a line. So if you want a literal '$' in your pattern, you need to use an escape sequence of \$. And in the context of a String literal, this needs an additional backslash to avoid interpretation as a Unicode escape or character escape -- that is, \\$.

Or, ever since JDK 1.5 you can use the replace() method rather than replaceAll(). Despite its name, the real difference is that replace() doesn't treat the first argument as a regular expression. So it's simpler, but less powerful.
