Chapter $7$ Programming Challenge $17$ Starting Out With Java Tony Gladdis $4$th Edition $-$ Must follow Templates and added specifications ADDED SPECIFICATIONS: Must create a class Array$2$D for the methods defined in the textbook.

Must add additional getAllRowTotals$()$ method to Array$2$D which returns an array of answers, e$.$g$.,$ the $0$ index of the returned array is the total for row $0$ of the array passed to it$.$

Must add additional getAllColTotals$()$ method to Array$2$D which returns an array of answers, e$.$g$.,$ the $0$ index of the returned array is the total for col $0$ of the array passed to it$.$

Must create a class Array$2$DTest to exercise methods defined in Array$2$D$.$ Array$2$D must be usable without instances.

Array$2$D methods shall assume that the arrays are of ints.

Must not have the same conceptual task coded in more than one place.

Array$2$DTest has getInput$()$ method that defines the $2$D array$$s values and passes that array back to main$()$ via a return statement.

Input is hard$-$coded with the values, i$.$e$.,$ declare & define a $3-$row, $4-$col $2$D array with values. I will then paste in my own set of values for testing. So code robustly, i$.$e$.,$ do NOT code assuming that the $2$D array is $3$x$4.$

Array$2$DTest has output$()$ method that receives the $2$D array of initial values and displays a report of the lowest, highest, total, count, and average for each array separately and displays the cumulative totals for each row and column. The data for this output will be obtained by output$()$ by directly calling the appropriate Array$2$D class methods.

Have Array$2$D make use of the method$($s$)$ of the previous assignment. TEMPLATES HERE: ARRAY DATA TEMPLATE: public class Ch$07$Pc$11\_$ArrayDataTEMPLATE
