本文通过实例代码给大家介绍了Java判断字符串是否含有乱码的方法，代码简单易懂，非常不错，具有一定的参考借鉴价值，需要的朋友参考下吧
具体代码如下所示：
/** * 判断字符是否是中文 * * @param c 字符 * @return 是否是中文 */ public static boolean isChinese(char c) { Character.UnicodeBlock ub = Character.UnicodeBlock.of(c); if (ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS || ub == Character.UnicodeBlock.CJK_COMPATIBILITY_IDEOGRAPHS || ub == Character.UnicodeBlock.CJK_UNIFIED_IDEOGRAPHS_EXTENSION_A || ub == Character.UnicodeBlock.GENERAL_PUNCTUATION || ub == Character.UnicodeBlock.CJK_SYMBOLS_AND_PUNCTUATION || ub == Character.UnicodeBlock.HALFWIDTH_AND_FULLWIDTH_FORMS) { return true; } return false; } /** * 判断字符串是否是乱码 * * @param strName 字符串 * @return 是否是乱码 */ public static boolean isMessyCode(String strName) { Pattern p = Pattern.compile("s*|t*|r*|n*"); Matcher m = p.matcher(strName); String after = m.replaceAll(""); String temp = after.replaceAll("p{P}", ""); char[] ch = temp.trim().tochararray(); float chLength = ch.length; float count = 0; for (int i = 0; i 0.4) { return true; } else { return false; } } public static void main(String[] args) { System.out.println(isMessyCode("韩顺平")); System.out.println(isMessyCode("你好")); }
