[Solved]Java Rewrite Lines 10 25 Fig 163 Concise Using Aslist Method Linkedlist Constructor Takes Q37275995

in java, Rewrite lines 10–25 in Fig. 16.3 to be more concise byusing the asList method and the LinkedList constructor that takes aCollection argument.

// Fig. 16.3: ListTest.java
// Lists, LinkedLists and ListIterators.
import java.util.List;
import java.util.LinkedList;
import java.util.ListIterator;

public class ListTest {
public static void main(String[] args) {
// add colors elements to list1
String[] colors =
{“black”, “yellow”, “green”, “blue”, “violet”, “silver”};
List<String> list1 = new LinkedList<>();

for (String color : colors) {
list1.add(color);
}

// add colors2 elements to list2
String[] colors2 =
{“gold”, “white”, “brown”, “blue”, “gray”, “silver”};
List<String> list2 = new LinkedList<>();

for (String color : colors2) {
list2.add(color);
}

list1.addAll(list2); // concatenate lists
list2 = null; // release resources
printList(list1); // print list1 elements

convertToUppercaseStrings(list1); // convert to uppercasestring
printList(list1); // print list1 elements

System.out.printf(“%nDeleting elements 4 to 6…”);
removeItems(list1, 4, 7); // remove items 4-6 from list
printList(list1); // print list1 elements
printReversedList(list1); // print list in reverse order
}

// output List contents
private static void printList(List<String> list) {
System.out.printf(“%nlist:%n”);

for (String color : list) {
System.out.printf(“%s “, color);
}

System.out.println();
}

// locate String objects and convert to uppercase
private static void convertToUppercaseStrings(List<String>list) {
ListIterator<String> iterator = list.listIterator();

while (iterator.hasNext()) {
String color = iterator.next(); // get item
iterator.set(color.toUpperCase()); // convert to upper case
}
}

// obtain sublist and use clear method to delete sublistitems
private static void removeItems(List<String> list,
int start, int end) {
list.subList(start, end).clear(); // remove items
}

// print reversed list
private static void printReversedList(List<String> list){
ListIterator<String> iterator =list.listIterator(list.size());

System.out.printf(“%nReversed List:%n”);

// print list in reverse order
while (iterator.hasPrevious()) {
System.out.printf(“%s “, iterator.previous());
}
}
}
