数组操作

1 数组倒叙：Snippet181

写道

int[] order = table.getColumnOrder();
for (int i = 0; i < order.length / 2; i++) {
int temp = order[i];
order[i] = order[order.length - i - 1];
order[order.length - i - 1] = temp;
}

 

2 数组增加，排序 写道

data = new int[0];
// add 10 random numbers to array and sort
int grow = 10;
int[] newData = new int[data.length + grow];
System.arraycopy(data, 0, newData, 0, data.length);
int index = data.length;
data = newData;
for (int j = 0; j < grow; j++) {
data[index++] = random.nextInt();
}
Arrays.sort(data);
