java - 使用java中的数组打印水平和垂直图中的数字图

Question

import java.util.Scanner;

public class Assignment5 {
  public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    int a;

    System.out.println("Please enter a number between 1 and 9:");
    int[] graph = new int[10];
    for(int i = 0; i < 10; ++i){
      a = scan.nextInt();
      graph[i] = a;
    }
  }

  // this is the method I'm required to use for 
  // this array assignment

  public static void printVertical(int[] graph){
    for(int i = 0; i < graph.length; i++){
      for(int j = 0; j < graph[i]; j++){
        System.out.print(" " + graph[i]);
      }
      System.out.println();
    }
  }

  // this is what I've got for the horizontal method

  // I took the for loop and nested for loop from the vertical.
  // I'm stuck on changing the variable to flip the graph -90 degrees

  public static void printHorizontal(int[] graph){
    for(int i = 0; i < graph.length; i++){
      for(int h = 0; h < graph[i]; h++){
        System.out.print(" " + graph[i]);
      }
      System.out.println();
    }
  }

  public static int calculateTotal(int[] graph){
    int sum = 0;
    for( int num : graph ){
      sum = sum + num;
    }
    System.out.print("The total is: " + sum);
    return sum;
  }
}

printVertical 方法中的 for 循环未正确返回图形。

我做错了什么？

输出需要如下所示:

    Sample output:
    2 4 6 8 9 8 6 4 3 2
    ---- Vertical Graph ----
    2 2
    4 4 4 4
    6 6 6 6 6 6
    8 8 8 8 8 8 8 8
    9 9 9 9 9 9 9 9 9
    8 8 8 8 8 8 8 8
    6 6 6 6 6 6
    4 4 4 4
    3 3 3
    2 2

    ---- Horizontal Graph ----

            9
          8 9 8
          8 9 8
        6 8 9 8 6
        6 8 9 8 6
      4 6 8 9 8 6 4 
      4 6 8 9 8 6 4
    2 4 6 8 9 8 6 4 2

    The total is: 52
    2 4 6 8 9 8 6 4 2

考虑下面给出的代码。它可能会解决您的问题..

import java.util.Scanner;
public class Assignment5 {
public static void main(String[] args) {

    Scanner scan = new Scanner(System.in);

    int a;
    System.out.println("Please enter a number between 1 and 9:");
    int[] graph = new int[10];
    for(int i = 0; i < 10; ++i){
        a = scan.nextInt();
        graph[i] = a;
    }
    System.out.println("----------Vertical Graph-------------");
    printVerticalGraph(graph);
    System.out.println("----------Horizontal Graph-------------");
    printHorizontalGraph(graph);
}
    public static void printVerticalGraph(int[] graph)
    {
        for (int i = 0 ; i < graph.length; i++)
        {
            for (int j = 0 ; j < graph[i] ; j++)
            {
                System.out.print(graph[i]+" ");
            }
            System.out.println();
        }
    }
    public static void printHorizontalGraph(int[] graph)
    {
        for (int i = 0 ; i < graph.length; i++)
        {
            for (int j = 0 ; j < graph.length; j++ )
            {
                if (i > 10 - graph[j])
                {
                    System.out.print(graph[j]);
                }
                else
                    System.out.print( " ");
                System.out.print(" ");
            }
            System.out.print("\n");
        }
    }
}

这是示例输出..

Please enter a number between 1 and 9:
2
4
6
8
9
8
6
4
3
2
----------Vertical Graph-------------
2 2
4 4 4 4
6 6 6 6 6 6
8 8 8 8 8 8 8 8
9 9 9 9 9 9 9 9 9
8 8 8 8 8 8 8 8
6 6 6 6 6 6
4 4 4 4
3 3 3
2 2
----------Horizontal Graph-------------


        9
      8 9 8
      8 9 8
    6 8 9 8 6
    6 8 9 8 6
  4 6 8 9 8 6 4
  4 6 8 9 8 6 4 3
2 4 6 8 9 8 6 4 3 2
