数组和普通的 Java 对象类似，只有一点点不同——追踪 Class 类的getName()方法就可以印证这一点。If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more '[' characters representing the depth of th...
System.out.println(s);意思是标准输出s到打印台上,我们看看具体执行的步骤: publicvoidprintln(Object x){//首先调用String类的valueOf方法,获得s的字符串表现形式Strings=String.valueOf(x);synchronized(this) {//打印print(s);//换行newLine(); } } 我们继续看看这个valueOf是怎么一回事: publicstaticString...

executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object ...
