Use Java to code the following:

Define utilizing 1D Arrays in Java as vectors to discuss linear algebra concepts

TASK #1

Create a static method that accepts 3 integer parameters and returns a 1D integer array containing the parameters as elements in the array. Numbers should be assigned indexes in order [0] [1]etc.

TASK #2

Create a static method that accepts no parameters and returns a 1D integer array containing randomly-generated values between 0 and 9. Numbers should be assigned indexes in order [0] [1]etc.

TASK #3

Create a static method that accepts a 1D integer array and returns a double which is square root of the sum of the squared values in the array. This represents the magnitude of a vector.

TASK #4

Create a static method that accepts two 1D integer array and returns a new 1D integer array which is the result of adding the two parameter arrays together.
