Write a method manyStrings that takes an ArrayList of Strings and an integer n as parameters and that replaces every String in the original list with n of that String. For example, suppose that an ArrayList called "list" contains the following values:
("squid", "octopus")
And you make the following call:
manyStrings(list, 2);
Then list should store the following values after the call:
("squid", "squid", "octopus", "octopus")
As another example, suppose that list contains the following:
("a", "a", "b", "c")
and you make the following call:
manyStrings(list, 3);
Then list should store the following values after the call:
("a", "a", "a", "a", "a", "a", "b", "b", "b", "c", "c", "c")
You may assume that the ArrayList you are passed contains only Strings and that the integer n is greater than 0.
ManyStringsTest.java
import java.util.ArrayList;
public class ManyStringsTest {
public static void main(String[] args) {
ArrayList<String> list = new ArrayList<String>();
list.add("squid");
list.add("octopus");
manyStrings(list, 2);
System.out.println(list);
}
public static void manyStrings (ArrayList<String> list, int n) {
for(int i=0;i<list.size();i++){
for(int j=1;j<n;j++){
list.add(i,list.get(i));
}
i+=n-1;
}
}
}
Output:
[squid, squid, octopus, octopus]

1. Write a program to input a list of names (strings) from the user and store them in an ArrayList. The input can be terminated by entering the empty string or byentering the string “quit”.2. Add further functionality to your program so that it searches the ArrayList to find the first string and the last string according to dictionary ordering and then prints out these strings (names). Do this exercise without sorting the names in the ArrayList. For example, if...
A java exercise please! Write a static method named swapHavles that takes an ArrayList of integers as a a parameter and returns a new ArrayList that has every element in the second half of the original ArrayList swapped with every element in the first half of the original ArrayList. Note: • You can assume that the ArrayList passed to this method as a parameter always contains an even number of elements and will always contain at least two elements. For...
//Java (Sort ArrayList) Write the following method that sorts an ArrayList: public static > void sort(ArrayList list) Write a test program that does the following operations: 4. Creates an empty ArrayList of Integer elements; 5. Generates 20 integer values, drawn at random between 0 and 9 (included), and adds them to the array list; 6. Calls the method sort and prints both the original list, and the sorted one.
Write an implementation of the following Java method: /* search(ArrayList, int key) -> int method is passed an array list of integers and an integer key method searches for the key in the array list and returns: the index of the key if it is in the array list -1 otherwise */
Write a java project that reads a sequence of up to 25 pairs of names and postal (ZIP) codes, street address, city, state, and 10-digit phone number for individuals. Store the data in an object designed to store a first name (string), last name (string), and postal code (integer), street address (string), city( string), state (string), and 10-digit phone number (long integer, contains area code and does not include special characters such as '(', ')', or '-' . Assume each...
Write a method public static ArrayList merge(ArrayList a, ArrayList b) that merges two array lists, alternating elements from both array lists. If one array list is shorter than the other, then alternate as long as you can and then append the remaining elements from the longer array list. For example, if a is 1 4 9 16 and b is 9 7 4 9 11 then merge returns the array list 1 9 4 7 9 4 16 9 11...

JAVA Write a program which will read a text file into an ArrayList of Strings. Note that the given data file (i.e., “sortedStrings.txt”) contains the words already sorted for your convenience. • Read a search key word (i.e., string) from the keyboard and use sequential and binary searches to check to see if the string is present as the instance of ArraryList. • Refer to “SearchInt.java” (given in “SearchString.zip”) and the following UML diagram for the details of required program...
2a) Write a method countEvens that takes an ArrayList of String objects as input and returns the number of even length strings contained in the input. For example, if the input is [ one, peach, pear, plum ] then countEvents(inp) should return 2. 2b) Write a method, mirror, that doubles the size of a list of integers by appending a mirror image of the list. For example, given an array list containing [ 1, 5, 2, 6 ], the method...
