Design a class named location for locating a maximal value and its location in a twodimensional array. the class contains public data field’s row, column, and maxvalue that store the maximal value and its indices in a two-dimensional array with row and column as int types and maxvalue as a double type. write the following method that returns the location of the largest element in a two – dimensional array: public static location locatelargest(double[][] a) the return value is an instance of location. write a test program that prompts the user to enter a two-dimensional array and display the location of the largest element in the array. here is the sample run: enter the number of rows and columns in the array: 3 4 enter the array:
a. 23.5 35 2 10
b. 4.5 3 45 3.5
c. 35 44 5.5 9.6 the location of the largest element 45 is at (1, 2)

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
