当我进入这个

INSERT INTO works_on
(essn, pno, hours)
values
('123456789', 1, 32.5),
('123456789', 2, 7.5),
('666884444', 3, 40.0),
('453453453', 1, 20.0),
('453453453', 2, 20.0),
('333445555', 2, 10.0),
('333445555', 3, 10.0),
('333445555', 10, 10.0),
('333445555', 20, 10.0),
('999887777', 30, 30.0),
('999887777', 10, 10.0),
('987987987', 10, 35.0),
('987987987', 30, 5.0),
('987654321', 30, 20.0),
('987654321', 20, 15.0),
('888665555', 20, 0);

我得到了跟随错误

ORA-00933:SQL命令未正确结束

如何在java中将数字转换为符号？例如,而不是2到**,或3到***等.

如何将数字转换为直方图？直方图应根据该值的滚动次数显示2-12的条形图.目前我的输出就像第二张图片,但假设看起来像第一张图片.谢谢.

我想添加每个州的投票总数和这个二维数组的每个候选人的总和.

这些是要求:

• 修改程序,以便显示每个州投票的总票数
  (即,每行添加一列,汇总每个州所有候选人的总投票数)

• 修改程序,以便显示每个候选人的总投票数(即,添加最后一行,显示所有三列投票的总投票数)

  public static void main(String[] args) throws IOException
  {
  // TODO code application logic here
  File election = new File("voting_2008.txt");
  Scanner sc = new Scanner(election);
  
  String[] states = new String[51];
  int[][]votes = new int[51][4];
  int[] Totalbystate = new int[votes.length];
  
  for (int s=0; s < 51; s++)
  {
      states[s] = sc.nextLine();
  }
  
  for(int c=0; c < 3; c++)
  {
      for(int s=0; s < 51; s++)

我正在尝试确定对线性和二进制搜索技术进行了多少次比较.谁能告诉我如何打印出每个案例发生循环的次数？例如,要在第一个数组中找到5,循环只发生一次.

       public static void main(String[] args) {
    // TODO code application logic here
    int[] values  = {5, 8, 6, 2, 1, 7, 9, 3, 0, 4, 20, 50, 11, 22, 32, 120};
    int[] valuesSorted  = {1, 2, 3, 4, 5, 8, 16, 32, 51, 57, 59, 83, 90, 104};
    DisplayArray(values);
    DisplayArray(valuesSorted);

    int index;
    index = IndexOf(1, values);
    System.out.println("1 is at values location " + index);
    index = IndexOf(120, values);

    System.out.println("120 is at values location " + index);

    index = BinaryIndexOf(104, …

如何将数字转换为符号？我的任务的最后一部分是这样的:直方图应根据该值的滚动次数显示2-12的条形图.如下所示: 目前我的输出是这样的:
