Create a user defined class for Exception for age, if age is negative throw an exception that age cannot be less than zero?

Write a program in C# to implement the operator overloading for the greater than (>) and assignment (=) operators

. Write a java program that specifies three parallel one dimensional arrays name length, width, and area. Each array should be capable of holding a number elements provided by user input. Using a for loop input values for length and width arrays. The entries in the area arrays should be the corresponding values in the length and width arrays (thus, area[i] = length [i]* width [i]) after data has been entered display the following output:

Length Width Area

-------- -------- -------

25 2.6 65.00

18.2 4.9 89.18

Sample Run1 Enter the array size: 5

Enter the Length and Width for Rectangle 1: 25 2.6

Enter the Length and Width for Rectangle 2: 18 4.9

Enter the Length and Width for Rectangle 3: 100 3.27

Enter the Length and Width for Rectangle 4: 1.84 7.4

Enter the Length and Width for Rectangle 5: 56 9.5 Output1:

Length Width Area

-------- -------- -------

25 2.6 65.00

18.2 4.9 89.18

100 3.27 327.00

1.84 7.4 13.62

56 9.5 532.00

2.   Create a java program that initialize a two dimensional array with the continuous assessment marks used to determine the semester mark for PRG510S exam qualification, The system should also create an array of student names in correspondence to the marks (Note: the appropriate weights of each individual assessment are given under corresponding headings and both the marks and student names are read from the user input).
