Transpose of a Matrix in Java Example

Algorithm for Transpose of a Matrix:

step 1: read r, c

step 2: create an integer array a[][] of size r,c

step 3: create an integer array b[][] of size c,r

step 4: initialize i=0

step 5: repeat through step-10 while (i < r)

step 6: initialize j=0

step 7: repeat through step-9 while (j < c)

step 8: read a[i][j]

step 9: j=j+ 1

step 10: i=i+ 1

step 11: reset i=0

step 12: repeat through step-17 while (i < r)

step 13: reset j=0

step 14: repeat through step-16 while (j < c)

step 15: b[j][i]=a[i][j]

step 16: j=j+ 1

step 17: i=i+ 1

step 18: initialize i=0

step 19: repeat through step-25 while (i < c)

step 20: move to new line

step 21: initialize j=0

step 22: repeat through step-24 while (j < r)

step 23: print b[i][j]

step 24: j=j+ 1

step 25: i=i+ 1

step 26: Exit

Here is the Java Example for Transpose of a Matrix:

import java.util.Scanner;
 class TransposeMatrix
 {
             public static void main(String args[])
        {
             int i,j,t,r,c ;
             Scanner s1=new Scanner(System.in);
             System.out.print("Enter the size of Rows : ");
             r=s1.nextInt();
             System.out.println("Enter the size of Columns :");
             c=s1.nextInt();
             System.out.println("\nThe Elements into the Array:->");
             int a[][]=new int[r];
             int b[][]=new int[r];
             for(i=0;i<r;i++)
             for(j=0;j<c;j++)
             a[i][j]=s1.nextInt();
             System.out.println("\nThe elements of Array\n");
             for(i=0;i<r;i++)
                 {
                    System.out.print("\n");
             for(j=0;j<c;j++)
                 {
                    System.out.print(a[i][j]+"\t");
                 }
                    for(i=0;i<r;i++)
                   {
                    for(j=0;j<c;j++)
                       {
                          b[j][i]=a[i][j];
                       }
                    }
             System.out.println("\nAfter Transfering print the data :->");
                     for(i=0;i<c;i++)
                        {
                           System.out.print("\n");
                           for(j=0;j<r;j++)
                               {
                                 System.out.print(b[i][j]+"\t");
                                }
                         }
                     }
        }
 }
