How can Java transform vertical data into horizontal data?

You can use a two-dimensional array to convert vertical data into horizontal data.

Here is a sample code:

public class TransposeArray {
    public static void main(String[] args) {
        int[][] verticalData = {
                {1, 2, 3},
                {4, 5, 6},
                {7, 8, 9}
        };

        int[][] horizontalData = transpose(verticalData);

        for (int i = 0; i < horizontalData.length; i++) {
            for (int j = 0; j < horizontalData[i].length; j++) {
                System.out.print(horizontalData[i][j] + " ");
            }
            System.out.println();
        }
    }

    public static int[][] transpose(int[][] verticalData) {
        int rows = verticalData.length;
        int columns = verticalData[0].length;

        int[][] horizontalData = new int[columns][rows];

        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                horizontalData[j][i] = verticalData[i][j];
            }
        }

        return horizontalData;
    }
}

This code represents vertical data containing 3 rows and 3 columns as a two-dimensional array. It then uses the transpose method to convert the vertical data into horizontal data and prints the result.

The output results in:

1 4 7 
2 5 8 
3 6 9
