1. Write a java program to display the A) Arithmetic exception. B) Array bounds exception. C) String bounds exception. Using try and catch. 2. Write a Java program to find the evaluation of quadratic equation using methods. (Provided – a=2,b=6 and c=8) . 3.Using Java Biuild Rectangle class will also have the following methods: Specification: setLength- The setLength method will store a value in an object’s length field. setWidth- The setWidth method will store a value in an object’s width field. getLength- The getLength method will return the value in an object’s length field. getWidth- The getWidth method will return the value in an object’s width field. getArea- The getArea method will return the area of the rectangle, which is the result of the object’s length multiplied by its width.

Zybooks C++ 1.7 LAB: Introduction to data structures labs Step 1: Producing correct output Three commented-out lines of code exist in main(). Uncomment the lines and click the "Run program" button. Verify that the program's output is: 2 + 2 = 4 Unknown function: PrintPlus2 Secret string: "abc" Submit your code for grading. Your submission will pass the "Compare output" test only, achieving 1 of the possible 10 points. Step 2: Inspecting the LabPrinter class Inspect the LabPrinter class implemented in the LabPrinter.h file. Access LabPrinter.h by clicking on the orange arrow next to main.cpp at the top of the coding window. Member functions Print2Plus2() and PrintSecret() print strings using std::cout. Step 3: Implementing CallFunctionNamed() Remove the three uncommented lines from main(). Then implement the CallFunctionNamed() function in main.cpp to handle three cases: If functionName is "Print2Plus2", call printer's Print2Plus2() member function. If functionName is "PrintSecret",…

7. Write a function that evaluates the area of a pentagon. Use "math.pi", for pi, and "math.sqrt" for square root. Write the solution on the space provided below. You do not need to run the code. 311 3.2 (Geometry: area of a pentagon) Write a program that prompts the user to enter the length from the center of a pentagon to a vertex and computes the area of the pen- tagon, as shown in the following figure. The formula for computing the area of a pentagon is Area 3√3 2 -s², where s is TT the length of a side. The side can be computed using the formula s = 2r sin 5' where r is the length from the center of a pentagon to a vertex. Here is a sample run: Enter the length from the center to a vertex: 5.5 Enter The area of the pentagon is 108.61

Minutes(using Pointers) by Catherine Arellano Write a program that will accept an integer value from 0000 to 2359. It will then extract the first 2 values of the integer to be the hours, and the last 2 to be the minutes. Implement the following functions: void extracts(int* time, int* hour, int* min); /* extract the hours and minutes from the time and stores the result to the address of hour and min respectively.*/ void display (int* hour, int* min); /*display the hours and minutes*/ Note: You are not allowed to edit main.c and Time.h. Input A time in format HHMM 1430 Output Hours and minutes Hour: 14 Minutes: 30 main.c Time.h 1 #include 2 #include "Time.h" 3 int main(void) { M456909 7 8 } int time, hour, min; scanf("%d",&time); extracts (time, &hour, &min); display (&hour, &min); return 0;

4.10 LAB: All permutations of names   Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will read a list of one word names, then use a recursive function to create and output all possible orderings of those names separated by a comma, one ordering per line. When the input is: Julia Lucas Mia then the output is (must match the below ordering): Julia, Lucas, Mia Julia, Mia, Lucas Lucas, Julia, Mia Lucas, Mia, Julia Mia, Julia, Lucas Mia, Lucas, Julia def print_all_permutations(permList, nameList):    # TODO: Implement method to create and output all permutations of the list of names. if __name__ == "__main__":     nameList = input().split(' ')    permList = []    print_all_permutations(permList, nameList)
