我想在JTextArea中打印字符串并正确对齐它们.很难解释所以我会上传我想要实现的屏幕截图.

因此,每行打印的字符串都是从Paper对象打印出来的,该对象具有参数(id,title,author,date,rank).数据从文本文件中读取,并使用loadPaper()函数存储在LinkedList中.

然后displayPapers()函数用于向JTextArea显示Paper对象的内容.displayPapers()如下所示:

/** Print all Paper object present in the LinkedList paperList to textArea */
public void displayPapers(){
    // clear textArea before displaying new content
    displayTxtArea.setText("");

    Paper currentPaper;
    ListIterator<Paper> iter = paperList.listIterator();

    while(iter.hasNext()){
        currentPaper = iter.next();
        String line = currentPaper.toString();

        if("".equals(line)){
            continue;
        } // end if

        String[] words = line.split(",");
        displayTxtArea.append   ("  " 
                                + padString(words[0],30) 
                                + padString(words[1],30) 
                                + "    " 
                                + padString(words[2],30) 
                                + "  " 
                                + padString(words[3],30)  
                                + padString(words[4],30) 
                                + "\n");

        System.out.println(words);
        //displayTxtArea.append(currentPaper.toString());
    } // end while

    displayTxtArea.append("  Total …
