Given:Which code, inserted at line 15, allows the class Sprite to compile?() A.Foo { public int bar() { return 1; }B.new Foo { public int bar() { return 1; }C.new Foo() { public int bar() { return 1; }D.new class Foo { public int bar() { return 1; }

下面程序执行后,baz的值应是______。 public class Test9 { public static void main(String[] args) { int index = 1; int fox[] = new int [3]; iht bar = fox [index]; int baz = bar + index; System.out.println(baz); } }A.0B.1C.2D.编译错误

关于以下初始化序列的执行结果的说法正确的是( )。 int index=1; int[] foo=new int[3]; int bar=foo[index]; int baz=bar+index;A.baz的值为0B.baz的值为1C.编译通过,但产生异常D.编译不能通过

下列程序执行后,baz的值应是 int index=1; int fox[ ]=new int[3]; Int bar=fox[index]; int baz:bar+index;A.0B.1C.2D.编译错误
