Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this...

Define static variables.

Explain using an example: a class, an object and different types of constructors. PS: Java

C++ Define a problem with input, output, and Inheritance. If no output explain the reason why and what you are going to do make sure it does not happen again aka learning from your mistakes.Problem:Design:Code:Output:

Consider the following skeletal C program: void fun1(void); /* prototype */void fun2(void); /* prototype */void fun3(void); /* prototype */void main() { int a, b, c; . . .}void fun1(void) { int b, c, d; . . .}void fun2(void) { int c, d, e; . . .}void fun3(void) { int d, e, f; . . .}Given the following calling sequences and assuming that dynamic scoping is used, whatvariables are visible during the execution of the last function? Include with each visible variablethe name of the function in which it was defined.a. main calls fun1; fun1 calls fun2; fun2 calls fun3.b. main calls fun1; fun1 calls fun3.c. main calls fun2; fun2 calls fun3; fun3 calls fun1.d. main calls fun3; fun3 calls fun1.e. main calls fun1; fun1 calls fun3; fun3 calls fun2. Consider the following program, written in JavaScript-like syntax: // main programvar x, y, z;function sub1() {var a, y, z;. . .}function sub2() { var a, b, z; . . .}function sub3() { var a, x, w; . . .}Given the following calling sequences and...

A class is a specification—a blueprint—for one or more objects. shows how a Thermostat class, for example, might look in C++.
