# Hello,I have an assignment which is doing writing two codes in java

First code: Mean and Standard DeviationWrite a program that prompts the user for 10 floating point values. The program should invoke two methods to calculate the mean and standard deviation of the numbers. You can use the formula below to calculate the mean and standard deviations. You will need: A scanner object to read the 10 values. An array to store the ten values

Two methods that do the following: Accepts an array and returns the mean. Accepts an array and returns the standard deviation. Comments where necessary. A sample of the output is shown below: Enter ten numbers: 1.9 2.5 3.7 2 1 6 3 4 5 2. The mean is 3.1100000000000003The standard deviation is 1.5573838462127583 ——————————————————————————————————————————————————————–

Second code: Sum of two matricesWrite a program that accepts two 3 x 3 matrices and invokes a method to add them together. The formula for adding two matrices is shown below: You will need: A scanner object to read the values that fill the arraysThree 2-dimensional arrays: One to store the values in the first 3×3 matrixOne to store the values in the second 3×3 matrix.

One to store the sum of the values from the first two matrices. A method that adds the two matrices using the formula above. Comments where necessary. A sample of the output is shown below:Enter matrix1: 1 2 3 4 5 6 7 8 9Enter matrix2: 1 2 3 4 5 6 7 8 9.

The addition of the matrices is 1.0 2.0 3.0 1.0 2.0 3.0 2.0 4.0 6.0 4.0 5.0 6.0 + 4.0 5.0 6.0 = 8.0 10.0 12.0 7.0 8.0 9.0 7.0 8.0 9.0 14.0 16.0 18.0Tip: You may prefer to print the results out this way instead:Enter matrix1: 1 2 3 4 5 6 7 8 9Enter matrix2: 1 2 3 4 5 6 7 8 9The addition of the matrices is 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 + 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 = 2.0 4.0 6.0 8.0 10.0 12.0 14.0 16.0 18.0
