    public static void main(String[] args) {
        //使用replaceAll
        String text = "Our line rackets \rthe encouraged symmetry.\n";
        String result = text.replaceAll("\n", "").replaceAll("\r", "");
        System.out.println(result);
        String randomSentence = "The backed valley manufactures \r"
                + "a politician above \n" + "a scratched body.";
        //google guava
        result = CharMatcher.breakingWhitespace().removeFrom(randomSentence);
        System.out.println(result);
        //apache commons
        String randomSentence2 = "The pocket reflects "
                + "over an intimate. \r";
        result = StringUtils.chomp(randomSentence2);
        System.out.println(result);
    }
}

结果

Our line rackets the encouraged symmetry.
Thebackedvalleymanufacturesapoliticianaboveascratchedbody.
