In C and C++, NULL, 0 and '\0' are all the same. In Java, 0 and '\0' are the same but null is something completely different; it has no ASCII value because ASCII values are only available for chars. null is not a char. SCJP 1.4 - SCJP 6 - SCWCD 5 - OCEEJBD 6 - OCEJPAD...
ASCII编码和Unicode编码的区别:ASCII编码是1个字节,而Unicode编码通常是2个字节。字母A用ASCII编码是十进制的65,二进制的01000001;字符0用ASCII编码是十进制的48,二进制的00110000,注意字符'0'和整数0是不同的;汉字中已经超出了ASCII编码的范围,用Unicode编码是十进制的20013,二进制的01001110 00101101。 你可以猜测,...

Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. But these can also be overused and fall into some common pitfalls. To get a better understandi...
它包括ASCII码范围内的所有可打印字符,如字母、数字、标点符号等,但不包括空格和控制字符。 std::regex可以用于匹配和提取符合特定模式的字符串。它提供了一系列成员函数和操作符,用于进行正则表达式的匹配、替换、提取等操作。使用std::regex,可以通过编写正则表达式模式来定义匹配规则,并通过调用相应的成员函数来执行...
