can you please write the code in java and explain

this is the result it needs to output

1. Download ComputeMeanDeviation.java from MS Methods module in folio. 2. Modify the program by adding the following two methods: public static double mean (int boundary, int n) public atatic double deviation (int boundary, int n) In the mean method, generate n ruedom integers e[0, boumdary ], compute and return the result of the mean. In the deviation method, generate n random integers [0, boundary ], compute and return the result of the atandard deviation. The formulas to compute the mean and the standard deviation are: mean=ni=1nx1deviation=n1i=1nx12n(inx1)2 3. Rewrite the main method so that it invokes the mean and deviation methods and displays the results of the mean and the standard deviation. A sample main method is as follows. Please type this main method in your own source code. public ztatie void main (string() aege) \& (f) Find mean double meanvalue in man (99,1000) ?
