1.
public String whatAmI(E e) {
//.getClass() returns the runtime class of an object
//.equals() determines whether two objects are equivalent
//by calling a new static instance of a wrapper object we can analyze
//it's class type and compare it to the variable passed in
if(e.getClass().equals(new Integer(1).getClass())) {
return "Integer";
}
else if(e.getClass().equals(new String("1").getClass())) {
return "String";
}
else if(e.getClass().equals(new Double(1.0).getClass())) {
return "Double";
}
else {
return "Who knows!";
}
}
2.
public String reverseWord(String word) {
Stack<Character> stack = new Stack<Character>();
for (int i = 0; i < word.length(); i++) {
stack.push(word.charAt(i));
}
String result = "";
while (!stack.isEmpty()) {
result += stack.pop();
}
return result;
}
Answer:
A. PRL
Explanation:

With the limitation of fluctuation, a mobile phone was made to adapt to this problems, thereby combining this broadbands like CDMA, GSM,4G LTE etc gave rise to PRL (Preferred roaming list) database to hold information needed to establish connection to the correct cell tower for these broadbands.
