如果您想获取行，您需要从每个数组中获取值，然后从这些值中创建一个新数组。你可以手动指定值，或使用一个for循环，像这样......

int[][] MyMat = {

{0,1,2,3,4}, {9,8,7,6,5}};

// get your columns... (easy)

int[] My0= MyMat[0]; //My0 = {0,1,2,3,4}

int[] My1= MyMat[1]; //My1 = {9,8,7,6,5}

// get the rows... (manually)

int[] My_0= new int[]{MyMat[0][0],MyMat[1][0]}; //My_0 = {0,9}

int[] My_1= new int[]{MyMat[0][1],MyMat[1][1]}; //My_1 = {1,8}

int[] My_2= new int[]{MyMat[0][2],MyMat[1][2]}; //My_2 = {2,7}

int[] My_3= new int[]{MyMat[0][3],MyMat[1][3]}; //My_3 = {3,6}

int[] My_4= new int[]{MyMat[0][4],MyMat[1][4]}; //My_4 = {4,5}

// get the rows... (as a for-loop)

int size = MyMat.length;

int[] My_0 = new int[size]; //My_0 = {0,9}

int[] My_1 = new int[size]; //My_1 = {1,8}

int[] My_2 = new int[size]; //My_2 = {2,7}

int[] My_3 = new int[size]; //My_3 = {3,6}

int[] My_4 = new int[size]; //My_4 = {4,5}

for (int i=0;i

My_0[i] = MyMat[i][0];

My_1[i] = MyMat[i][1];

My_2[i] = MyMat[i][2];

My_3[i] = MyMat[i][3];

My_4[i] = MyMat[i][4];

}

否则，改变你的整个阵列，使其存储{row,column}代替{column,row}，像这样...

int[][] MyMat = {

{0,9},{1,8},{2,7},{3,6},{4,5}};

// get the rows... (easy)

int[] My_0= MyMat[0]; //My_0 = {0,9}

int[] My_1= MyMat[1]; //My_1 = {1,8}

int[] My_2= MyMat[2]; //My_2 = {2,7}

int[] My_3= MyMat[3]; //My_3 = {3,6}

int[] My_4= MyMat[4]; //My_4 = {4,5}

// get the columns... (manually)

int[] My0= new int[]{MyMat[0][0],MyMat[1][0],MyMat[2][0],MyMat[3][0],MyMat[4][0]}; //My0 = {0,1,2,3,4}

int[] My1= new int[]{MyMat[0][1],MyMat[1][1],MyMat[2][1],MyMat[3][1],MyMat[4][1]}; //My1 = {9,8,7,6,5}

// get the columns... (as a for-loop)

int size = MyMat.length;

int[] My0 = new int[size]; //My0 = {0,1,2,3,4}

int[] My1 = new int[size]; //My1 = {9,8,7,6,5}

for (int i=0;i

My0[i] = MyMat[0][i];

My1[i] = MyMat[1][i];

}

请注意，不可能使用简写，这将使您可以轻松地获取行和列 - 您必须决定哪些是您想要的，并将数组结构化为这种格式。
