给定下面方法声明,与该方法重载的方法包括[br][/br]public void close(int apple){}
A: public int close(int a){}
B: public void close(int a, int b){}
C: public void close(int door){
System.exit(0);
}
D: public void close(float door){}
E: public void close(double b, Boolean b){}
A: public int close(int a){}
B: public void close(int a, int b){}
C: public void close(int door){
System.exit(0);
}
D: public void close(float door){}
E: public void close(double b, Boolean b){}
举一反三
- 给定下面方法声明，与该方法重载的方法包括 public void close(int apple){} A: public int close(int a){} B: public void close(int a， int b){} C: public void close(int door){ System.exit(0); } D: public void close(float door){} E: public void close(double b, Boolean b){}
- class MethodOverload{[br][/br]public void setValue(int a, int b, float c){}[br][/br]}[br][/br]下列哪个方法定义是setValue的重载方法: ( ) A: public void setValue(int a, int c, float b){} B: public void setVar(int a, int b){} C: public int setValue(int a, float c, int b){return a;} D: public float set (int a, int c, float b){return a;}
- 下列( )选项不是InputStream类中的方法。 A: public abstract int read( ) throws IOException B: public final void writeInt (int throws IOException C: public void close( )throws IOException D: public int available( )throws IOException
- 现有[br][/br] public class Parent{[br][/br] public void change (int x){[br][/br] }[br][/br] }[br][/br] public class Child extends Parent{[br][/br] //覆盖父类change方法[br][/br] }[br][/br]下列哪个声明是正确的覆盖了父类的change方法 A: protected void change (int x){} B: public void change(int x, int y){} C: public void change (int x){} D: public void change (String s){}
- 下面( )函数是public void example(){...}的重载函数。 A: public void example( int m){...} B: public int example(){...} C: public void example2(){...} D: public int example ( int m, float f){...}
