我需要幫助我的Stack類鏈接到我的測試牀類

Question

import java.util.Random; 

public class TestBed { 

public static void main(String a[]) { 
    // creating the array 
    int[] array = new int[100]; 
    Random random = new Random(); 
    // changing the variable of my clone array for reference 
    int[] arr = cloneArray(array); 

    for (int i1 = 0; i1 < 100; i1++) 
     array[i1] = random.nextInt(100) + 1; 
    // print out of bubble sort before and after the sort 
    System.out 
      .println("***********************Bubble Sort   ****************************"); 
    arr = cloneArray(array); 
    System.out.println("Values Before the sort:\n"); 
    printArray(arr); 
    System.out.println(); 
    bubble_srt(arr); 
    System.out.print("Values after the sort:\n"); 
    printArray(arr); 
    // print out of selection sort before and after the sort 
    System.out.println(); 
    System.out 
      .println("********************Selection Sort*****************************"); 
    System.out.println(" Selection Sort\n\n"); 
    arr = cloneArray(array); 
    System.out.println("Values Before the sort:\n"); 
    printArray(arr); 
    System.out.println(); 
    selection_srt(arr); 
    System.out.print("Values after the sort:\n"); 
    printArray(arr); 

    System.out.println(); 

    Stack stack = new Stack(); 



} 




public static int[] buildArray(int bound) { 
    return null; 
} 

// clone array as a data type 
public static int[] cloneArray(int[] data) { 
    return (int[]) data.clone(); 
} 

// print array as a data type 
public static void printArray(int[] data) { 

    // while there are still numbers left in the array print out the next 
    // value 

    for (int i = 0; i < data.length; i++) 
     System.out.print(data[i] + " "); 

} 

// bubble syntax 
public static void bubble_srt(int a[]) { 
    int t = 0; 
    for (int i = 0; i < a.length; i++) { 
     for (int j = 1; j < (a.length - i); j++) { 
      if (a[j - 1] > a[j]) { 
       t = a[j - 1]; 
       a[j - 1] = a[j]; 
       a[j] = t; 
      } 
     } 
    } 
} 

// selection syntax 
public static void selection_srt(int array[]) { 
    for (int x = 0; x < array.length; x++) { 
     int index_of_min = x; 
     for (int y = x; y < array.length; y++) { 
      if (array[index_of_min] > array[y]) { 
       index_of_min = y; 
      } 
     } 
     int temp = array[x]; 
     array[x] = array[index_of_min]; 
     array[index_of_min] = temp; 
    } 
} 


} 

在這裏，我必須將我的Stack類，但我不知道如何獲得2類在一起正確即時通訊新的節目和我的學校我扔進這是高對我來說，現在我是個Java類中卡住5周

public class Stack { 
Node top; 
int size; 

public Stack() { 
    top = null; 
    size = 0; 
} 

public int pop() { 
    if (top != null) { 
     int item = top.data; 
     top = top.next; 
     size--; 
     return item; 
    } 
    return -1; 
} 

public void push(int data) { 
    Node t = new Node(data); 
    t.next = this.top; 
    this.top = t; 
    size++; 
} 

public boolean isEmpty() { 
    return size <= 0; 
} 

public int getSize() { 
    return size; 
} 

public int peek() { 
    return top.data; 
} 

public void printStack() { 
    Node n = this.top; 
    int pos = this.getSize(); 
    while (pos > 0) { 
     System.out.println("Position: " + pos + " Element: " + n.data); 
     if (pos > 0) { 
      n = n.next; 
     } 
     pos--; 

    } 
} 
} 

class Node { 
public int data; 
public Node next; 

Node(int d) { 
    data = d; 
    next = null; 
} 

public int getData() { 
    return data;`enter code here` 
}`enter code here` 

{ 
    Stack s = new Stack(); 
    s.push(9); 
    s.push(2); 
    s.push(7); 
    s.push(3); 
    s.push(6); 
    s.push(4); 
    s.push(5); 
    System.out.println("Size is: " + s.getSize()); 
    // s.printStack(); 
    int size = s.getSize(); 
    for (int i = 0; i < size; i++) { 
     System.out.print(s.pop() + " "); 
    } 

} 
}

在Stack類文件的開頭，創建一個包名稱，例如：在您的測試牀

package com.example.testcode; 

然後class文件，導入你的Stack類f rom包，例如：

import com.example.testcode.Stack;
