Java 获取循环以添加数组的所有列

我试图获取一个硬编码数组，并打印出每列的所有和。每次我尝试它只是在结束前反复打印第一列和。我不知道还要添加什么来保持循环在整个阵列中运行

代码如下：

公共类气候变化{
公共静态void main（字符串[]args）{
最终整数行=9；
最终整数列=12；
int[][]位移={
{106, 107, 111, 133, 221, 767, 866, 1001, 172, 307, 392, 395},
{20, 73, 26, 82, 502, 615, 209, 947, 116, 214, 278, 445},
{163, 203, 276, 308, 172, 246, 354, 118, 123, 310, 146, 152},
{121, 260, 234, 108, 149, 202, 216, 58, 567, 229, 628, 765},
{1203, 1274, 1226, 1882, 1072, 1007, 1192, 1395, 123, 310, 146, 152},
{116, 324, 438, 714, 167, 521, 209, 904, 76, 29, 31, 99},
{76, 29, 31, 99, 187, 201, 278, 306, 183, 122, 99, 246},
{109, 104, 121, 13, 121, 69, 246, 100, 123, 161, 69, 246},
{402, 415, 209, 547, 106, 234, 178, 145, 103, 121, 39, 246}};
字符串[]动物={
“猎豹”，
“老虎”，
“亚洲象”，
“瓦基塔鼠海豚”，
“山地大猩猩”，
“红金枪鱼”，
“猩猩”，
“黑犀牛”，
“海豚”}；
系统输出打印项次（“温度0C 1C 3C”+
“5C 7C 9C 28C 32C 36C 38C 42C 45C”）；
System.out.println（）；
对于（int i=0；i

每次我尝试使用它时，它只是在打印的数组下面一遍又一遍地打印第一列和。

解决方案 如果很接近，则必须在内部循环中构建和，然后在外部循环中打印出和。 还请注意，您必须在outerloop中将其再次重置为零

for (row = 0; row < displaced.length; row++) {
    colSum = 0;

    for (col = 0; col < displaced.length; col++) {
        colSum = colSum + displaced[row][col];

    }
    System.out.println("Animals:  " + colSum);
    colSum = 0;
}
