1.Write a java code to print Multiplication Table Till 20 HINTS:
public static void main(String[ ] args) {
int multiplicationTable[ ][ ]=new int [21][11];
2.Write a java code to find the minimum value from the array.
HINTS:
public static void main(String[ ] args) {
int arr[ ][ ] = {{1, 5, 8},
{-1, 15, 81},

Using least squares fitting, you are to fit the data sets to the following models and solve for the parameters ai , where i is the index of the parameter. the input/output data for the systems are linked in the bblearn site. for each of the systems use matlab to plot the supplied data vs. the model fit on one plot. include your code in the solutions. (a) linear fit "lineardata.mat" y=a1x^3 + a2x^2 + a3x + a4 (b) plant fit "plantdata.mat g(s) = a1/(s + a2)

Write a defining table and then a program that determines if you can sleep in or not. your program should get all its input from your computer’s clock. on all weekdays (monday through friday) that are not holidays, your program should output “get up! ” on all other days (weekends and holidays), your program should output “sleep in.” the three holidays that your program must check for are january 1 (new year’s day), july 4 (u.s. independence day), and december 25 (christmas). you don’t need to include other holidays in your program because most other holidays do not occur on a fixed day each year.
