InputStream is = new java.io.ByteArrayInputStream(string.getBytes());
ExprLexer lexer = new ExprLexer(is);

No need to rewrite the Lexer.

One of the Lexer's constructors takes a java.io.Reader as its parameter. java.io.StringReader is derived from Reader and thus may be passed to this constructor. So you can just do:

    Your_Lexer lexer = new Your_Lexer(new StringReader("your string here"));

Hope this helps...
