Write a program in java to accept and
store the number in a 4x4 matrix in a DDA. Find the transpose in a matrix by
using an assignment statement. The transpose of a matrix is obtain when we
change row elements and column and vice versa.
ALGORITHM
STEP 1:- Start.
STEP 2:- Declare transpose as a
class.declare and initialize variables i,j arr[][],trp[][].
STEP 3:- Declare trans as a method with return type void ..now enter the
elements of 4*4 square matrix using
nested loop...inner loop on j strating with 0 and upto less than 4 incremented
by 1 and outer loop on i strating with 0 and upto less than 4 incremented by 1
in each step....along with the message " ENTER THE NUMBER OF MATRIX 4*4".
STEP 4:- Now display the array elements in the form of square matrix along
with the message "the user given matrix- ".
STEP 5:- Now within the nested loop (inner loop on j strating with 0 and
upto less than 4 incremented by 1 and outer loop on i strating with 0 and upto
less than 4 incremented by 1 in each step) store the value of square matrix
a[i][j] in trp[j][i].
STEP 6:- Now again start a nested loop print the transpose of the user
given matrix along with the message "transpose of the given matrix".
STEP 7:- Now close the method trans().
STEP 8:- Now declare main() function.. create object ob of the class
transpose and call the method trans()
through the object ob.
STEP 9:- Now close the main function and the class transpose.
STEP 10:- Stop.
