A: 无法编译
B: foo的值是true
C: foo的值是false
D: foo的值是0
举一反三
- Given: int index = 1; boolean[] test = new Boolean; boolean foo= test [index]; What is the result?
- test = new Boolean; boolean foo= test [index]; What is the result?
- int index = 1； int [] foo = new int [3]； int bar = foo [index]； int baz = bar + index； What is the result？（） A: Baz has the value of 0 B: Baz has the value of 1 C: Baz has the value of 2 D: An exception is thrown. E: The code will not compile.
- 以下代码片段的输出结果为( ). [script type="text/javascript"] var foo =1; function Test(){ alert(foo); var foo=2; alert(foo); } Test(); </script A: 1,2 B: 2,1 C: 1,undefined D: undefined,2
- 以下代码片段的输出结果为( ). [script type="text/javascript"] var foo =1; function Test(){ alert(foo); var foo=2; alert(foo); } test(); </script A: 1,2 B: 2,1 C: undefined,2 D: 没有任何结果

下面程序段的运行结果为（） int index=1; int[] foo=new int[3]; int bar=foo[index]; int baz= bar+index;

读代码: public class Test { public static void main (String args[]) { class Foo { public int i = 3; } Object o = (Object) new Foo(); Foo foo = (Foo)o; System.out.println(foo.i); } } 结果是：

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0 B: baz的值为1 C: 编译通过，但产生异常 D: 编译不能通过

int index = 1； int foo = new int ； int bar = foo [index]； int baz = bar + index； What is the result？（） A: Baz has the value of 0 B: Baz has the value of 1 C: Baz has the value of 2 D: An exception is thrown. E: The code will not compile.
