無法在Java中的組合框中的項目

Question

我是完全新的Java Swing，我試圖適合我的字典在組合框中，當我開始在JTextField中輸入，並且它從組合框的開始索引鍵入的組合框中搜索它單詞和顯示我開頭的單詞，現在問題是我不能在組合框中添加我的字典項目，我將字典單詞提取到一個字符串數組，然後在ComboBox中添加，但它沒有顯示任何內容，而我能夠添加其中約20件物品，ComboBox的物品空間是否有限？如果是的話，那麼請參考我可以製作這種類型的其他方法。 這裏的我在做什麼

package swing; 

import java.io.BufferedReader; 
import java.io.FileNotFoundException; 
import java.io.FileReader; 
import java.io.IOException; 
import java.util.logging.Level; 
import java.util.logging.Logger; 

public class swing1 extends javax.swing.JFrame { 

    /** 
    * Creates new form swing1 
    */ 
    public swing1() throws FileNotFoundException { 
     initComponents(); 

     FileReader fileread=null; 
      String array[]=new String[107186]; 
      String input; 
      String FileName="English.txt"; 
      fileread = new FileReader(FileName); 

      BufferedReader br = new BufferedReader(fileread); 
      int i=0; 
      try { 
       while((input=br.readLine())!=null) 
       { 
        array[i]=input; 
        i++; 
       } 
      } catch (IOException ex) { 
       ex.printStackTrace(); 
      } 

      this.jComboBox1.addItem(array); 
    } 

    /** 
    * This method is called from within the constructor to initialize the form. 
    * WARNING: Do NOT modify this code. The content of this method is always 
    * regenerated by the Form Editor.

     jComboBox1.addActionListener(new java.awt.event.ActionListener() {

       jComboBox1ActionPerformed(evt); 
      }

} 

我不能上傳圖片，由於我的名聲小於10，但告訴你答案，這讓我這個在組合框中「[Ljava.lang.String; @ 43376」 我正在使用Netbeans並使用拖放操作來製作GUI，並且我還將字典元素放在組合框屬性的模型中，但它沒有給我所期望的結果

幫幫我！

我建議你使用

 JComboBox<String> jComboBox1 = new JComboBox<String>(); 
    //loop over your array and add them one by one 
    for(String s:array) 
     jComboBox1.addItem(s);
