Wie erzeugt man horizontale und vertikale Linien mit einer for-Schleife?

Question

Also das ist meine Klasse. Ich versuche, die print() - Methode auszudrucken, um eine horizontale Linie über meinem Array und eine andere Linie unter meinem Array auszudrucken. Ich möchte auch vertikale Linien zwischen jeder Zahl in meinem Array haben. Okay, ich habe meine horizontalen Linien fixiert. Jetzt bin ich nur darüber verloren, wie ich vertikale Linien am Anfang und am Ende meiner Arrays platzieren kann.

public class Array{ 

private int[] array; 

public Array(int numElements) 
{ 
    array = new int[numElements]; 
} 

public void fill() 
{ 
    for (int i = 0; i < array.length; i++) 
    { 
     array[i] = (int) (10*Math.random()); 
    } 
} 

public void print() 
{ 
    for(int x = 0; x < 2*array.length; x++) 
    { 
     System.out.print("-"); 
    } 
    System.out.println(); 

    for(int i = 0; i < array.length; i++) 
    { 
     System.out.print(array[i]); 
     if(i == array.length - 1) 
     { 
      System.out.println(); 
     } 
     else 
     { 
      System.out.print("|"); 
     } 
    } 

    for(int n = 0; n < 2*array.length; n++) 
    { 
     System.out.print("-"); 

    } 
    System.out.println(); 
} 

public void sort() 
{ 
    int n = array.length; 
    boolean swapped; 

    do 
    { 
     swapped = false; 

     for(int i = 1; i < n; i++) 
     { 
      if(array[i-1] > array[i]) 
      { 
       int tmp = array[i]; 
       array[i] = array[i-1]; 
       array[i-1] = tmp; 
       swapped = true; 
      } 
     } 
    } while(swapped); 
} 

public void printFrequency() 
{ 
    int[] countArray = new int[10]; 
    for(int x : array) 
    { 
     countArray[x]++; 
    } 
    for(int i = 0; i < 10; i++) 
    { 
     System.out.println("There are " + countArray[i] + ", " + i + "'s "); 
    } 
} 
} 

Das ist mein Ausgang:

Answer 1

Verschieben Sie die Linie System.out.println(); außerhalb des for-Schleife, wenn Sie wollen nicht erstellen eine neue Zeile nach jedem Bindestrich.

Answer 2

nehmen Sie die println() aus dieser Schleife:

for(int n = 0; n < array.length; n++) 
{ 
    System.out.print("-"); 
    System.out.println(); 
}
