Answer 1

배열을 채우기위한 가장 쉬운 모드 :

int rows = 30; 

int[][] itemsSold = new int[rows][6]; 

for (int i = 0; i < rows; i++) { 
    itemsSold[rows][0] = venta; 
    itemsSold[rows][1] = ventac; 
    itemsSold[rows][2] = ventas; 
    itemsSold[rows][3] = ventau; 
    itemsSold[rows][4] = ventab; 
    itemsSold[rows][5] = ventag; 

    //Change the variables 
    //venta = ... 
    //... 
}
