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);
