Write a Java program for manipulating matrices of integers.
Your program must prompt the user for a single-character
transaction code or Ctrl-Z to quit. The transaction codes are:
N (New matrix)
L (print Last matrix)
A (print All matrices in the matrix vector)
S (print Sum of last two matrices)
C (Clear the matrix vector)
If the user enters "N" your program must read the row and column
specification of the new matrix, then the rows of the matrix, and
then enter the matrix into a matrix vector.
If the user enters "L" your program must print the last matrix
entered into the matrix vector.
If the user enters "A" your program must print all the matrices in
the matrix vector.
If the user enters "S" your program must print the sum of the last
two matrices in the matrix vector. If the vector contains less
than two matrices your program should do nothing.
If the user enters "C" your program must clear the matrix vector of
all previously entered matrices.
