Java Program to Find Transpose of a Matrix
A Java program to find the transpose of a matrix.
Problem Description
Write a Java program to find the transpose of a matrix.
Code
public class TransposeMatrix {
public static void main(String[] args) {
int row = 2, column = 3;
int[][] matrix = { {2, 3, 4}, {5, 6, 4} };
// Display current matrix
display(matrix);
// Transpose the matrix
int[][] transpose = new int[column][row];
for(int i = 0; i < row; i++) {
for (int j = 0; j < column; j++) {
transpose[j][i] = matrix[i][j];
}
}
// Display transposed matrix
display(transpose);
}
public static void display(int[][] matrix) {
System.out.println("The matrix is: ");
for(int[] row : matrix) {
for (int column : row) {
System.out.print(column + " ");
}
System.out.println();
}
}
}Output
The matrix is:
2 3 4
5 6 4
The matrix is:
2 5
3 6
4 4 Explanation
- Transpose: Swapping rows and columns.
- Logic:
transpose[j][i] = matrix[i][j].
