JAVA-无法从另一个数组正确填充多维数组

Question

I have a string of values separated by commas that I converted into an array, which I was then going to use to create a 2D array. When creating a loop to add the data from the first array to the 2D array it is repeating the data.

The output I'm getting is:

4428,40,401,610,2016,3821,31,347,572,2015,4381,38,341,520,2014,2536,17,193,290,2013,4295,39,371,552,2012,4643,45,343,502,2011,3922,28,312,475,2010,4434,30,350,541,2009,4038,28,341,536,2008,218,1,20,28,2007,46,0,6,15,2006,65,0,9,16,2005,4428,40,401,610,2016,3821,31,347,572,2015,4381,38,341,520,2014,2536,17,193,290,2013,4295,39,371,552,2012,4643,45,343,502,2011,3922,28,312,475,2010,4434,30,350,541,2009,4038,28,341,536,2008,218,1,20,28,2007,46,0,6,15,2006,65,0,9,16,2005,4428,40,401,610,2016,3821,31,347,572,2015,4381,38,341,520,2014,2536,17,193,290,2013,4295,39,371,552,2012,4643,45,343,502,2011,3922,28,312,475,2010,4434,30,350,541,2009,4038,28,341,536,2008,218,1,20,28,2007,46,0,6,15,2006,65,0,9,16,2005,4428,40,401,610,2016,3821,31,347,572,2015,4381,38,341,520,2014,2536,17,193,290,2013,4295,39,371,552,2012,4643,45,343,502,2011,3922,28,312,475,2010,4434,30,350,541,2009,4038,28,341,536,2008,218,1,20,28,2007,46,0,6,15,2006,65,0,9,16,2005,4428,40,401,610,2016,3821,31,347,572,2015,4381,38,341,52 0,2014,2536,17,193,290,2013,4295,39,371,552,2012,4643,45,343,502,2011,3922,28,312,475,2010,4434,30,350,541,2009,4038,28,341,536,2008,218,1,20,28,2007,46,0,6,15,2006,65,0,9,16,2005

and the correct output should be:

4428,40,401,610,2016,3821,31,347,572,2015,4381,38,341,520,2014,2536,17,193,290,2013,4295,39,371,552,2012,4643,45,343,502,2011,3922,28,312,475,2010,4434,30,350,541,2009,4038,28,341,536,2008,218,1,20,28,2007,46,0,6,15,2006,65,0,9,16,2005

Expected results:

{{4428,40,401,610,2016}

{3821,31,347,572,2015}

{4381,38,341,520,2014}

...} and so on, every 5

My code for adding the array to the 2D array is below:

 {String[] columns = {"Yards","Touchdowns","Attempts","Incompletions","Year"};



String[] data1 = results1.split(",");

Object [][] data11 = new Object[columns.length][data1.length];
for(int i = 0; i<columns.length;i++){
    for(int j = 0; j<data1.length;j++){
    data11[i][j] = data1[j];
    //System.out.print(data11[i][j]+",");
}
}}

EDIT: Solution!

Object [][] data11 = new Object[data1.length/columns.length][columns.length];
int column = -1;
for(int j = 0; j<data1.length;j++){
    if(j % columns.length == 0) column = column+1;
            data11[column][j % 5] = data1[j];
}

Answer 1

You also loop the first array (i), so he will repeat it. Just write this:

 data11[0][j] = data1[j];

Or even don't do the first loop at all, depending on what you need. Assuming your output, you only want to fill in the first position (0) of the array.

Answer 2

Maybe this work for you:

Object [][] data11 = new Object[columns.length][data1.length / 5];
int column = -1;
for(int j = 0; j<data1.length;j++){
    if(j % 5 == 0) column = column + 1
    data11[j % 5][column] = data1[j];
}

Note the matrix size changed and the assignation too. Haven't tried, probably you can make a prettier version. Hope it helps!
