10.3 下面定义的4个方法中不属于方法重载是( )
(1) void getNum(int a);
(2) int getNum(double a);
(3) void getNum(int b);
(4) double getNum(int a,double b);
(1) void getNum(int a);
(2) int getNum(double a);
(3) void getNum(int b);
(4) double getNum(int a,double b);
举一反三
- 现有如下代码 1: class Super{ 2: public float getNum(){return 3.0f;} 3: } 4: public class Sub extends Super{ 5: 6: } 在第5行加入下列哪行代码后会导致程序编译错误 A: public float getNum(){return 4.0f;} B: public void getNum(){} C: public void getNum(double d){} D: public double getNum(float d){return 4.0d;}
- } [br][/br]在第5行加入下列哪行代码后会导致程序编译错误 A: public float getNum(){return 4.0f;} B: public void getNum(){} C: public void getNum(double D: {} <br> <br>public double getNum(float d){return 4.0d;}
- 现有如下代码[br][/br]class Super{ [br][/br] public float getNum(){return 3.0f;} [br][/br] } [br][/br]public class Sub extends Super{ [br][/br] //【代码】[br][/br]} [br][/br]在【代码】标注行加入下列哪行代码后会导致程序编译错误 A: public float getNum(){return 4.0f;} B: public void getNum(){} C: public void getNum(double){} D: public double getNum(float d){return 4.0d;}
- 给出以下代码,请问以下哪些语句放置在第六行会引起编译错误?( )1.class Super{2.public float getNum(){return 3.0f;}3.}4.5.public class Sub extends Super{6.7}请选择一个正确答案。 A: (1)public float getNum() {return 4.0f;} B: (2)public void getNum(){} C: (3) public void getNumdouble (){} D: (4)public double getNumfoat (){return 4.0d;}
- 下列哪些函数与此函数void show(int a,char b,double c){}重载。 A: void show(int x,char y,double z){} B: int show(int a,char b,double c){} C: void show(int a,double c,char b){} D: void show(int a,double c){}
