如何使用对象打印Java中的一系列行'；s属性？

基本上，我有一个学生对象存储在数组列表中，具有以下属性：

-firstName: String
-lastName: String
-studentID: String
-row: int
-column: int

现在我想在控制台中以如下方式打印它们：

第一排

学生1 |学生2 |学生4

firstName1 | firstName2 | firstNamen

lastName1 | lastName2 | lastNamen

第二排

学生1 |学生2 |学生4

firstName1 | firstName2 | firstNamen

lastName1 | lastName2 | lastNamen

属性来自数据库并存储在学生对象中。 它们的存储方式是根据列和行号进行排列。现在，我想以这样的方式打印上面的内容：当row属性更改时，它将打印另一个“行”学生

编辑：我做了什么

   public void displayStudents() {
    studentListSize = StudentList.size();
    int listIndex = 0;                          // This variable gives you the size of the list
    int columnIndex = 0;                        // The column index gives you the column you are supposedly traversing
    int resetIndex = 0;                         // This index does what its name does which is essentially to reset a value
    int continueIndex = 0;                      // Index which tells one where one supposedly ended, hence the name 'continue'

    int currentRow = seats.get(columnIndex).getStudentRow();    // The currentRow method says which row one is currently traversing

    for(listIndex = 0; listIndex < seatSize; listIndex++) {
        // if the row attribute taken from the list of seats is not equal to the current row then, that means that the row has changed and 
        // the following loops execute 
        if(seats.get(listIndex).getStudentRow() != currentRow) {

            // The following methods just display stuff. It's essentially a looped version of the commented out method below
            System.out.println();
            for(columnIndex = resetIndex; columnIndex <= continueIndex; columnIndex++) {
                System.out.printf("|%10s|",  seats.get(columnIndex).getFirstName());
            }
            System.out.println();
            for(columnIndex = resetIndex; columnIndex <= continueIndex; columnIndex++) {
                System.out.printf("|%10s|",  seats.get(columnIndex).getLastName());
            }
            System.out.println();

        // setting the reset index to the column index is done because if you don't do this the for loops below will repeat the displayed things above with a new set of columns
        resetIndex = columnIndex;
        // this sets the currentRow
        currentRow = seats.get(listIndex).getStudentRow();
        // Print the IDs
        System.out.printf("|%10s|",  seats.get(listIndex).getStudentID());
        // the assignment below ensures that the all rows are printed (for the first set)
        continueIndex = listIndex;
    }

    // The next lines are workarounds which repeat what the above does. There could have been a better way had there been a functioning GOTO keyword in Java
    System.out.println();
    for(columnIndex = resetIndex; columnIndex <= continueIndex; columnIndex++) {
        System.out.printf("|%10s|",  seats.get(columnIndex).getFirstName());
    }
    System.out.println();
    for(columnIndex = resetIndex; columnIndex <= continueIndex; columnIndex++) {
        System.out.printf("|%10s|",  seats.get(columnIndex).getLastName());
    }
    System.out.println();

public void displayStudents（）{
studentListSize=StudentList.size（）；
int listIndex=0；//此变量提供列表的大小
int columnIndex=0；//列索引提供了假定要遍历的列
int resetIndex=0；//此索引执行其名称所执行的操作，本质上就是重置值
int continueIndex=0；//该索引告诉一个人应该在哪里结束，因此名为“continue”
int currentRow=seats.get（columnIndex）.getStudentRow（）；//currentRow方法表示当前正在遍历的行
对于（listIndex=0；listIndex对于（columnIndex=resetIndex；columnIndex注意，输出应该在命令行中什么类型的数据库？您根本没有发布任何代码。请告诉我们您首先尝试了什么。看起来第1行实际上是3行，第2行与第3行完全相同。嗯？！您能澄清一下如何将student对象存储在数组列表中吗属性？我用这些属性创建了一个学生对象，并将它们存储在一个列表中。
