以下哪段代码可以编译：

A、class A extends I { int value; void setValue(int val) { value = val; } int getValue() { return value; } }

B、class A extends I { void increment(); }

C、abstract class C implements I { int value; public void setValue(int val) { value = val; } public int getValue() { return value; } }

D、interface A implements I { void increment(); }

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

A、s3 = s1 + s2;

B、s3 = s1 - s2;

C、s3 = s1 & s2;

D、s3 = s1 . s2;

E、s3 = s1 $ s2;

F、s3 = s1 ^ s2;

G、s3 = s1 * s2;

A、s3 = s1 + s2;

B、s3 = s1 - s2;

C、s3 = s1 & s2;

D、s3 = s1 . s2;

E、s3 = s1 $ s2;

F、s3 = s1 ^ s2;

G、s3 = s1 * s2;

H、s3 = s1 # s2;

A、s3 = s1 + s2;

B、s3 = s1 - s2;

C、s3 = s1 & s2;

D、s3 = s1 . s2;

E、s3 = s1 $ s2;

F、s3 = s1 ^ s2;

G、s3 = s1 * s2;

H、s3 = s1 # s2;

A、s3 = s1 + s2;

B、s3 = s1 - s2;

C、s3 = s1 . s2;

D、s3 = s1 * s2;

A.编译出错

B.5752

C.true

D.无任何输出
