12. Program to Transpose matrix
💡Code:
import java.util.Scanner; public class TransposeMatrix7078 { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Get the dimensions of the matrix from the user System.out.print("Enter the number of rows: "); int rows = scanner.nextInt(); System.out.print("Enter the number of columns: "); int columns = scanner.nextInt(); // Create the matrix int[][] matrix = new int[rows][columns]; System.out.println("Enter elements for the matrix:"); inputMatrix(matrix, scanner); // Transpose the matrix int[][] transposedMatrix = transposeMatrix(matrix); // Display the original and transposed matrices System.out.println("Original Matrix:"); displayMatrix(matrix); System.out.println("Transposed Matrix:"); displayMatrix(transposedMatrix); // Close the scanner scanner.close(); } // Function to input elements into a matrix private static void inputMatrix(int[][] matrix, Scanner scanner) { for (int i = 0; i < matrix.length; i++) { for (int j = 0; j < matrix[0].length; j++) { System.out.print("Enter element at position [" + (i + 1) + "][" + (j + 1) + "]: "); matrix[i][j] = scanner.nextInt(); } } } // Function to transpose a matrix private static int[][] transposeMatrix(int[][] matrix) { int rows = matrix.length; int columns = matrix[0].length; int[][] transposedMatrix = new int[columns][rows]; for (int i = 0; i < rows; i++) { for (int j = 0; j < columns; j++) { transposedMatrix[j][i] = matrix[i][j]; } } return transposedMatrix; } // Function to display the elements of a matrix private static void displayMatrix(int[][] matrix) { for (int i = 0; i < matrix.length; i++) { for (int j = 0; j < matrix[0].length; j++) { System.out.print(matrix[i][j] + " "); } System.out.println(); } } }
