我想将每个州的投票总和加上这个二维数组的每个候选人的总和。
这些是要求:
- 修改程序,以便显示每个州的总票数
(即,在每一行添加一列,将每个州的所有候选人的总票数相加) 修改程序,以便显示每个候选人的总票数(即,添加最后一行显示所有三列选票的总票数)
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++) { votes[s][c] = sc.nextInt(); } } Formatter fmt = new Formatter(); fmt.format("%20s%12s%12s%12s%21s", "State", "Obama", "McCain", "Other", "Total by state"); System.out.println(fmt); for (int s=0; s < 51; s++) { fmt = new Formatter(); fmt.format("%20s", states[s]); System.out.print(fmt); for(int c=0; c < 3; c++) { fmt = new Formatter(); fmt.format("%12d", votes[s][c]); System.out.print(fmt); } int sum =0; for(int row=0; row < votes.length; row++) { for (int col=0; col < votes[row].length; col++) { sum = sum + votes[row][col]; } } fmt = new Formatter(); fmt.format("%21d", Totalbystate) ; System.out.println(); }
