JAVA In this exercise, you are given a phrase that starts with ‘A'. If the word after ‘A' begins with a vowel, add an ‘n' after the ‘A', otherwise, return the phrase as is. Example: grammer("A word") --> "A word" grammer("A excellent word") --> "An excellent word" public String grammar(String phrase) { }

import java.util.*;

public class Main

{

public static void main(String[] args) {

 System.out.println(grammar("A excellent word"));

}

public static String grammar(String phrase) {

    if (phrase.charAt(2) == 'a' || phrase.charAt(2) == 'e' || phrase.charAt(2) == 'i' || phrase.charAt(2) == 'o' || phrase.charAt(2) == 'u')

        return "An" + phrase.substring(1);

    else

        return phrase;

}

}

Explanation:

Create a function called grammar that takes one string parameter, phrase

Check if the character after "A", is one of the vowels, using charAt function. If it is, then insert "n" after "A". (To insert "n", concatenate two parts: "An", and the substring of the initial string after A).

Otherwise, return the initial string

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.

the answer will be d
