要在行中获得最大值，这相当容易，而且您的方法是正确的

int aMaxR1, aMaxR2, aMaxR3;
int aMinC1, aMinC2, aMinC3;

aMaxR1 = Collections.min(group.get(here could be first row));
aMaxR2 = Collections.min(group.get(here could be second row));
aMaxR3 = Collections.min(group.get(here could be third row));

aMaxC1 = Collections.max(group.get(here could be first column));
aMaxC2 = Collections.max(group.get(here could be second column));
aMaxC3 = Collections.max(group.get(here could be third column));

对于列，可以执行For循环：

aMaxR1 = Collections.max(group.get(0));

aMaxR1 = Collections.max(group.get(0));

 for(int i = 0; i < group.size(); i++){
     System.out.println(Math.max(Math.max(group.get(0).get(i), group.get(1).get(i)), group.get(2).get(i)));
  }
