Chapter 3.1, Problem 3SCP
Explanation of Solution
Nine mistakes:
- Mistake-1 in Line 5:
- When passing the arguments to the method, the data type is used.
- The user should not declare a parameter when passing the arguments.
- Mistake-2 in Line 5:
- The argument “y” is not declared and initialized before the method call.
- When the variable is passed as an argument to a method call it should be initialized.
- Mistake-3 in Line 6:
- The method header in line number “11” is defined with two parameters but program statement in line number “6”, the method is invoked only with one argument.
- The number of arguments in method call should be same as the number of parameters in the method header.
- Mistake-4 in Line 7:
- The method header in line number “11” is written with two parameters of type “double” but the method is invoked with two arguments of type “String” in line number “7”.
- The type of arguments should be same as the type of parameters in the method header.
- Mistake-5 in Line 8:
- The variable “z” used in line number “8” is not declared and initialized in this scope.
- The variable to be used in the print statement should be declared and initialized within that scope...
