可以使用文本编辑器(如Notepad++)来转换文件的编码,并去除BOM。 ## 3. 正则表达式检查非ASCII字符 在Java中,你可以使用正则表达式来检查字符串中是否存在非ASCII字符。以下是一个示例代码: ```java public class IllegalCharacterChecker { private static final Pattern NON_ASCII_PATTERN = Pattern.compile("[^\\...
usingintarithmetic, wheres[i]is the ith character of the string,nis the length of the string, and^indicates exponentiation. (The hash value of the empty string is zero.)” 对每个字符的ASCII码计算n – 1次方然后再进行加和,可见Sun对hashCode的实现是很严谨的. 这样能最大程度避免2个不同的String...
