Answer:
public static boolean beginsWithZ(String word){
if(string == null || string.length() == 0)
return 0;
if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')
return 1;
else
return 0;
}
Explanation:
This method is a boolean method, meaning it returns true if the string begins with Z or z and false otherwise. So:
The Java command charAt() let's you find the character at each position of the string, so i use it.
public static boolean beginsWithZ(String word){
if(string == null || string.length() == 0)
return 0;
if(word.charAt(0) == 'Z' || word.charAt(0) == 'z')
return 1;
else
return 0;
}
Answer: C. Cause and Effect Modelling.
Explanation:
Data Mining is a technique which aims at obtaining important and useful information in a stockpile of data. This in turn would prove useful in making predictions. It would also inform present decisions.
The Cause and Effect modelling approach explains that for every given action ( effect ), there was a prompting factor ( cause ).
In the case of Sendstars Company, the downward spiral in customer retention was as a result of ill -mannered staff. This effect, prompted the decision to have the employees trained on customer service.
