2.NUL没有被定义于C和C++,NUL是’\0’的名字,它不应该被直接使用除非你自己定义它,像:#define NUL ‘\0’。 字符串处理函数 1.strlen()函数 实参:字符数组名 / 字符串 函数作用:求字符串的长度(即字符串中包含的有效字符的个数。!!注意:不包括字符’\0’) //重点 ...
Notice how the owners() parameter takes a simple string as a default value while the type of the parameter is *array* of Strings. That's possible thanks to varargs, another J2SE 5.0 feature. (For more information about varargs and also the new enum facility used to define the Priority ...

The @SuppressWarnings annotation accepts a "value" variable that's an array of strings indicating the warnings that should be suppressed. The set of legal strings varies by the compiler, but on the JDK it's conveniently the same set of keywords that can be passed to -Xlint . Compilers are...
loadClass() 方法接收类名来加载类返回表示加载的类的java.lang.Class实例。事实上loadClass方法找到.class文件(或者URL)的实际字节,并调用defineClass方法来构造出java.lang.Class类的字节数组。加载器上调用loadClass方法的加载器称之为初始化加载器(即,JVM启动加载使用这个加载器). ...
Retains flexibility by allowing Java libraries to define the formatting syntax used in string templates. Simplifies the use of APIs that accept strings written in non-Java languages (e.g., SQL, XML, and JSON). Enables the creation of non-string values computed from literal text and embedded ...
