The most accurate and most boring way to (66) Java is that it is a new computer programming language developed by Sun Microsystems that creates (67) independent programs that can be distributed and run remotely. To run Java programs, a computer must have a Java interpreter. Currently (68) Java programs are small "applets" that are (68) as part of web pages.
When you use a Java (69) browser to view a Web page that includes a Java applet, the browser loads the applet onto your computer through your modem or network. Then the Java interpreter runs the applet, which could include animation or sound, on your computer rather than transmitting the code bit by bit over Internet. A few thousand bytes of Java code can turn into a powerful program on your computer.
So an applet could include (70) with Java interpreter.

阅读下面代码 class Test implements Runnable { public int run（ ） { int i=0； while(true) { i++; System.out.println("i="+i)； } } } 上述代码的编译结果是
A:程序通过编译，并且run()方法可以正常输出递增的i值 B:程序通过编译，调用run()方法将不显示任何输出 C:程序不能通过编译，因为while的循环控制条件不能为true D:程序不能通过编译，因为run()方法的返回值类型不是void
