求数组a[5][5]每行元素的平均值

public class test{
public static void main(String[] args){
int[][] nums = {
{1,2,3,4,5},
{2,3,4,5,6},
{3,4,5,6,7},
{4,5,6,7,8},
{5,6,7,8,9}
};

for(int i=0; i<nums.length; i++){
int tem = 0;
for(int j=0; j<nums[i].length; j++){
tem += nums[i][j];
}
tem = tem/nums[i].length;
System.out.println("第" + i + "行平均值" + tem);
}
}
}
