Java Program to Find Transpose of a Matrix

• Java program to print transpose of a matrix using for loop.

Transpose a matrix java: In this java program, we have to find the transpose matrix of a given M x N matrix. To find the transpose of a matrix, we will swap a row with corresponding columns, like first row will become first column of transpose matrix and vice versa. The transpose of matrix A is written A^T.

The i^th row, j^th column element of matrix A is the j^th row, i^th column element of A^T.

A[i][j] = AT[j][i];

            for (j = 0; j < 4; j++) {
                input[i][j] = scanner.nextInt();
            }

        // Generating Transpose of input matrix
        for (i = 0; i < 4; i++) {
            for (j = 0; j < 4; j++) {
                transpose[j][i] = input[i][j];

        System.out.println("Transpose Matrix");
        for (i = 0; i < 4; i++) {
            for (j = 0; j < 4; j++) {
                System.out.print(transpose[i][j] + " ");
            }
            System.out.print("\n");
        }
    }
}

Output
