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...
