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;…
Can you help me please: have the program know when numbers out of the array boundaries are received and mitigate those problems. The given code intentionally induces numbers out of bounds and the student’s portion must correct for this. As always use a header file and implementation file to do those calculations. Remember not to change the given code below in any way Design and implement the class myArray that solves the array index out of bounds problem and also allows the user to begin the array index starting at any integer, positive or negative. Every object of type myArray is an array of type int. During execution, when accessing an array component, if the index is out of bounds, the program must terminate with an appropriate error message. Consider the following statements:myArray list(5);                                  //Line 1 myArraymyList(2, 13);                     //Line 2myArray yourList(-5, 9);                    //Line 3The statement in Line 1 declares list to be an…

Use anyprimitive data type that you wish. The program should have the following methods:• getTotal. This method should accept a two-dimensional array as its argument andreturn the total of all the values in the array.• getAverage. This method should accept a two-dimensional array as its argument andreturn the average of all the values in the array.• getRowTotal. This method should accept a two-dimensional array as its first argumentand an integer as its second argument. The second argument should be the subscriptof a row in the array. The method should return the total of the values in thespecified row.• getColumnTotal. This method should accept a two-dimensional array…
despite that the array parameter is preceded by the const qualifier, the array elements can be modified in the function body. Select one: True False
Define the array printed below using the np.array() function, and assign it to the variable 'my_array' (only one line of code needed). [[0, 2, 4],[9, -6, 5],[0, 0, -10]]
8. Which of the following statement is correct? If we pass the reference using out, value should be initialized in the called method If we pass the reference using ref, value should be initialized in the called method Using ref we also can call a method by passing value O If we pass the reference using out, value should be initialized in the called method 9. While using params, the parameter can be a single variable, one dimensional array as well as a two-dimensional array. True False
Which of the following are true about arrays? Arrays are reference types. Array indexing is bounds‐checked. Arrays sometimes can be created without using new. The entire contents of an array can be copied via =.
What is the result when you use either the ref or out keyword with an array parameter?
Determine whether the following array declarations are valid. If a declaration is valid, write VALID. If it is invalid, you can make assumptions and write a correct declaration.
surve in your ive been made available. Each contains data for one household. A single record includes an integer identification number, the annual income for the household, and the number of members of the household. You may assume that no more than 25 households were surveyed. Write a program to store the survey results into an array of user-defined structures of type household. The program should input the survey results from the user._The program should also perform the following operations: (Your program must provide a function for each of the following operations) • Calculate the average household income, and list the identification number and income of each household whose income exceeds the average. • Calculate the percentage of households having incomes below the poverty level. The poverty level, P, may be computed using the formula P = 2000 + 1000 • (m – 2) where m is the number of members in the household. Sample Input 24 5000 4 36 10000 5 45 2000 4 50 4000 2 55 6000 4
Which of the following statements about arguments in functions is false? To pass an individual array element to a method, use only the name of the array. In Java, everything, including arguments, is a reference. O Arguments in Java are most often passed by value. O When an individual array element is passed to a method, it is passed by value.
