A class Trans is defined to find the transpose of a square matrix. A transpose of a matrix is obtained by interchanging

A class Trans is defined to find the transpose of a square matrix. A transpose of a matrix is obtained by interchanging the elements of the rows and columns.
  Example: If size of the matrix = 3, then
  
  Some of the members of the class are given below:
  Class name: Trans
  Data members/instance variables:
  arr[][]:to store integers in the matrix
  m:integer to store the size of the matrix
  Methods/Member functions:
  Trans(int mm): parameterised constructor to initialise the data member m = mm
  void fillarray():to enter integer elements in the matrix to create the transpose of the given matrix
  void transpose():to create the transpose of the given matrix
  void display():displays the original matrix and the transposed matrix by invoking the method transpose()
  Specify the class Trans giving details of the constructor(), void fillarray(), void transpose() and void display(). Define a main() function to create an object and call the functions accordingly to enable the task.

Solution:

 

  
  
  import java.util.*;
  class Trans{
      int arr[][],arr2[][];
      int m;
      public Trans(int mm) {
          m=mm;
          arr=new int[m][m];
          arr2=new int[m][m];
      }
  
      public void fillArray( ){
          Scanner sc = new Scanner(System.in);
  
          for(int i = 0; i < m; i++) 
          {
              for(int j = 0; j < m; j++) 
              {
                  System.out.println("Enter the "+i+j+" Element: ");
                  arr[i][j] = sc.nextInt();
              }
          }
      }
  
      
      public void transpose(){
          
          for(int i = 0; i < m; i++)
          {
              for(int j = 0; j < m; j++)
              {
                  arr2[i][j]=arr[j][i];
              }
          }
      }
      
      public void display() {
          for(int i = 0; i < m; i++)
          {
              for(int j = 0; j < m; j++)
              {
                  System.out.print(arr2[i][j] + "	");
              }
              System.out.println();
          }
      }
  
      public static void main(String args[])
      {
          Scanner sc = new Scanner(System.in);
          System.out.print("Enter number of rows and columns:");
          int m = sc.nextInt();
          Trans obj=new Trans(m);
          obj.fillArray();
          obj.transpose();
          obj.display();
          
      }
  }
