java怎样用常量接收集合中的信息？

Set seatRow = new HashSet();
Set seatCol = new HashSet();
int row = 9;  //can be argument in a method.
int col = 15; //can be argument in a method.
for (int i = 0; i < row; i++) {
    seatRow.add(i);
    for (int j = 0; j < col; j++) {
        seatCol.add(j);
        System.out.println(i + "-" + j);
    }
}

//check seat existing.
String selectedSeat = "5-19";  //surely, no such seat.
String[] selSeatStr = selectedSeat.split("-");
int selRow = Integer.parseInt(selSeatStr[0]);
int selCol = Integer.parseInt(selSeatStr[1]);
boolean have = seatRow.contains(selRow) && seatCol.contains(selCol);
Assert.assertFalse(have);

首先向list中放值

/**
* 将座位号放入ArrayList中
* @param row 座位的行数
* @param colu 座位的列数
* @return 设置好数据的List 
*/
 public List setList(int row, int colu){
     List<?> list = new ArrayList<?>();
     for(int i=1;i<row;i++){
        for(int j=1;j<colu;j++){
            String str = i+"-"+j;
            list.add(str);
        }
     }
 }

然后每次就遍历list就ok了，用contains方法.
