The following steps are needed.. ( use java)

1. Import scanner class

2. Create an instance of the scanner class (you need the main method)

3. Prompt the user to enter 4 ints (this can be done using a loop)

4. Save each int in variables: a,b,c,d

Your program should perform the followings: 1. Your program should prompt the user to enter the dimensions of the matrices (10 pts) 2. Checks the validity of the multiplication (10 Pts) 3. Use the random object to generate the data (20 pts) 4. Multiply the matrices (20 pts) 5. Format outputs nicely a. One copy to the screen (20 pts) b. Another copy to an external file created by your program (20 pts)
