问如何将一个2D阵列的每个I行与另一个2D阵列的每个I行连接起来

 int returnArray[] [] = new int[3][rowLength]; //new 2d array 

 for(int i=0; i<rowLength; i++){
      returnArray[0][i] = a[0][i]; //place a row one in new row 1
 }

 for(int i=0; i<rowLength; i++){
      returnArray[1][i] = b[0][i]; //place b row one in new row 2

 }

 for(int i=0; i<rowLength; i++){
      returnArray[2][i] = c[0][i]; //place c row one in new row 3

 }

 return returnArray;
