Rewrite the client program to use the Baby class that you have done using ArrayList.
You should also have the following function in this new client program:
a) Enter details for each baby (name and age) and thus populate the Baby ArrayList
b) Calculate and display the average age of all babies in the ArrayList
c) Ask the user to enter the name of a baby, and then remove it from the ArrayList
d) Allow the user to add new baby information in the ArrayList
e) Output the details of each baby from the ArrayList (name and age) Compare this client program using the ArrayList with the client program you have done using array, comment on the differences between the two.
Modify your client program in the last question, by adding a sort function such that when that option is selected, it sorts the ArrayList using the baby names in alphabetical order and output the details in the sorted ArrayList to a CSV (sortedbabylist.csv) file.
public class Baby {
private String name;
private int age;…
Salesforce Assignment:
You are working in company as a junior developer and the manger assign you a task to create the
test class of trigger code of the following code will cover all the use case like insert, update, delete.
The code is as follows:
public class TriggerBasicAssignmentTriggerHelper (
// This method is used to update the vlaue of field C
public static void getFiledvalue(List listofValues, Map mapofCoustomobject ){
for (Trigger_Basic_Assignments_ct :listofvalues){
if(mapofCoustomobject == null || t.Field_A_c != mapofCoustomobject.get(t.Id). Field_A_C || t.Field_8_c != mapofCoustomobject.get(t.I
if(t.Operator_ '+')
t.Field C_c = t.Field_A_c + t.Field_B_c;
else if(t.Operator_c *')
t. Field C_c = t.Field A_* t.Field_8_c;
else if(t.Operator_c == /' && t.Field B_c != 0)
t.Field C_c = t.Field A_c / t.Field_B_c;
else
t.Field C_c = t.Field_A_c - t.Field B_c;
I need the test class only.

A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]arrow_forward

Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]arrow_forward
