如何在同一行上打印数组和直方图？

Question

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;

public class Histogram
{
  public static void main(String[] args) throws FileNotFoundException
  {
    Row[] numbers = {
           new Row("1  -  10"), new Row("11 -  20"), new Row("21 -  30")                 
           new Row("31 -  40"), new Row("41 -  50"), new Row("51 -  60")
           new Row("61 -  70"), new Row("71 -  80"), new Row("81 -  90"),
           new Row("91 - 100")
                };
for(Row number : numbers)
  System.out.print(number);   
Counter section = new Counter();
section.StarCounter();

}

it prints out something like this:

1  - 10|
11 - 20|
21 - 30|
*****************
*********
***
ect.

I would like it to print out something like:

1  - 10|*****************
11 - 20|*********
21 - 30|***
ect.

thanks in advance for any pointers, I'm probably just overlooking the obvious.

Counter class:

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;


public class Counter
{
  public void StarCounter() throws FileNotFoundException
  {
    File file = new File("alotofnumbers.txt");
    Scanner scan = new Scanner(file);
    int[] integers = new int[1000];
    int start = 0;
    int count1 = 0;
    int count2 = 0;
    int count3 = 0;
    int count4 = 0;
    int count5 = 0;
    int count6 = 0;
    int count7 = 0;
    int count8 = 0;
    int count9 = 0;
    int count10 = 0;

    while (scan.hasNextInt())
    {
  integers[start++] = scan.nextInt();
}

for (int input : integers)
{
  if(input <= 10)
  {
    count1++;  
  }
  else if(input > 10 && input <= 20)
  {
    count2++;
  }
  else if(input > 20 && input <= 30)
  {
    count3++;
  }
  else if (input > 30 && input <= 40)
  {
    count4++;
  }
  else if (input > 40 && input <= 50)
  {
    count5++;
  }
  else if (input > 50 && input <= 60)
  {
    count6++;
  }
  else if (input > 60 && input <= 70)
  {
    count7++;
  }
  else if (input > 70 && input <= 80)
  {
    count8++;
  }
  else if (input > 80 && input <= 90)
  {
    count9++;
  }
  else if (input > 90 && input <= 100)
  {
    count10++;
  }
} 
  double counted1 = count1 / 2.7;
  double counted2 = count2 / 2.7;
  double counted3 = count3 / 2.7;

  {
   System.out.print("*");

  }
  System.out.println();


  for(int star = 0; star <= counted2 ; star++)
  {
    System.out.print("*");
  }

   System.out.println();
   for(int star = 0; star <= counted3 ; star++)
   {
    System.out.print("*");
   }

     System.out.println();

   for(int star = 0; star <= counted4 ; star++)
   {
     System.out.print("*");
   }

    System.out.println(); 
    for(int star = 0; star <= counted5 ; star++)
    {
     System.out.print("*");

      }

       System.out.println();     


 }
 }

Apparently my post has to much code and I don't really have much more info to give so it wants me to type something random up. public class Row { private String rows;

  public Row(String colums)
  {
  rows = colums ;
  }

  public String toString()
  {
  Counter section = new Counter();
  return rows + "|" + "\n";
  }

  public void setRow(String colums)
  {
  rows = colums;
  } 

  public String getRow()
  {
  return rows;
  }

  }

Here is a solution to your problem. The problem was that you were printing all of your Row data first and then all of your Integer data. You need to print them both at once. Not one after the other. Also just fyi, there is about a million different ways to make your initial code better. I would try and sit down and think of a better way to do this so you can learn (after you turn in your assignment so you are not rushed, we can all help. This is a good start though.)

First I erased the printing of the Row data, and added a constructor to your Counter class to take in your Row data.

Row[] numbers = {
        new Row("1  -  10"), new Row("11 -  20"), new Row("21 -  30"),                 
        new Row("31 -  40"), new Row("41 -  50"), new Row("51 -  60"),
        new Row("61 -  70"), new Row("71 -  80"), new Row("81 -  90"),
        new Row("91 - 100")
};  
Counter section = new Counter(numbers);
section.StarCounter();

New Constructor:

public class Counter
{
    Row[] numbers;
    public Counter(Row[] numbers) {
        this.numbers = numbers;
    }
    //Rest of your methods
}

Then printed the Row data when you print your Integer data.

System.out.print(numbers[0]);  //new line
for(int star = 0; star <= counted1  ; star++)
{
    System.out.print("*");
}
System.out.println();
System.out.print(numbers[1]);  //new line
for(int star = 0; star <= counted2 ; star++)
{
    System.out.print("*");
}
//Do the same for the rest

Hope this helps!

Oh also got rid of the newline in your Row class.

public String toString()
{
    return rows + "|";
}
