Question

a) Look at the following method header:

public static void showValue

The following code has a call to the showValue method. Fin the error.

int x =8;

showValue(int);     //Error!


b)Find the error in the following method definition:

public static double timesTwo(double num)

{

       double result = num*2;

}


For a, I think there is an error in the showValue(int); because it is suppose to be showValue(x); instead, but I'm not really sure.
For b, there is a semicolon missing on the first line. If anyone cal help?

Explanation / Answer

a)calling should be as

showValue(x); // because u have to put the value not datatype


b)

public static double timesTwo(double num)

{

double result = num*2;

return result; // here is error

}


in this all thing is ok ,,,,semicolon is not required in first line because

it is a method definition ..

altthough u have to return some value because method is returnig double
