下列程序中注释的那个代码是错误的？ abstract class Takecare{ protected void speakHello() {} public abstract static void cry(); static int f(){return 0;} abstract float g(); }
A: protected void speakHello() {}
B: public abstract static void cry();
C: static int f(){return 0;}
D: abstract float g();
A: protected void speakHello() {}
B: public abstract static void cry();
C: static int f(){return 0;}
D: abstract float g();
举一反三
- 下列接口中标注的（A,B,C,D）中，哪两个是错误的?interface Takecare { protected void speakHello(); public abstract static void cry(); int f(); abstract float g(); } A: protected void speakHello(); B: public abstract static void cry(); C: int f(); D: abstract float g();
- 下列程序中注释的哪个代码（A、B、C、D）是错误的？abstract class TakeCare{ abstract void speak(); //A public abstract static void cry(); //B static int f() {return 5;} //C abstract float g(); //D } A: A B: B C: c D: D
- 下列接口中标注的（A,B,C,D）中，哪两个是错误的? interface Takecare { protected void speakHello(); //A public abstract static void cry(); //B int f(); //C abstract float g(); //D }
- 下列接口中标注的（A,B,C,D）中，哪两个是错误的?interface Takecare { protected void speakHello(); //A public abstract static void cry(); //B int f(); //C abstract float g(); //D} A: A B: B C: C D: D
- 下列代码中标注的（A,B,C,D）代码中，哪一个是错误的? abstract class Test { protected void a() {} //A public abstract static void b(); //B static int c(){ return 0 ;} //C abstract float d(); //D } A: A B: B C: C D: D
