以下是接口I的定义:interface I{void setValue(int val);int getValue();}以下哪段代码能通过编译?()

A. class A extends I{int value;void setValue(int val) {value=val;}int getValue() {return value;}}
B. class B implements I{int value;void setValue(int val) {value=val;}}
C. interface C extends I{void increment();}
D. interface D implements I{void increment();}
