java中将语句/字符串转换为二维数组

public class StringTo2DArray {
    public static void main(String[] args) {
        String sentence = "Hello,World;How,are,you";
        String[][] array = convertTo2DArray(sentence, ",", ";");
        
        // 打印二维数组
        for (String[] row : array) {
            for (String element : row) {
                System.out.print(element + " ");
            }
            System.out.println();
        }
    }
    
    public static String[][] convertTo2DArray(String sentence, String rowDelimiter, String colDelimiter) {
        String[] rows = sentence.split(colDelimiter);
        int numRows = rows.length;
        int numCols = rows[0].split(rowDelimiter).length;
        
        String[][] array = new String[numRows][numCols];
        
        for (int i = 0; i < numRows; i++) {
            String[] elements = rows[i].split(rowDelimiter);
            for (int j = 0; j < numCols; j++) {
                array[i][j] = elements[j];
            }
        }
        
        return array;
    }
}
