输出中的换行符

我正在构建一个程序，通过GUI接收带有换行符的输入字符串，将其分成行，然后用单词分割，然后逐字传递给我仍需要实现的方法，{{1这将以某种方式接受一个单词并用适当的单词交换它。目前，使用以下代码：

translate

我发布了一张图片，但我没有足够的声誉。请注意，根据this question，我只是尝试将translate(System.lineSeparator())代替""<html><br/></html>""，但这也不起作用。我记得尝试过System.lineSeparator()回答命令并获得MultiLineUI或类似内容。

    @Override
    public void actionPerformed(java.awt.event.ActionEvent e) {

        inpText = inputField.getText();
        String[] lines = inpText.split("\n");
        String[][] words = new String[lines.length][20];
        for(int i=0;i<lines.length;i++){
            words[i] = lines[i].split(" ");
        }
        translate("<html>");
        for(int i=0;i<lines.length;i++){
            for(int j = 0;j<words[i].length;j++){
                translate(words[i][j] );
            }
            translate("<br/>");
        }
        translate("</html>");
    }

您可以尝试在您的内容周围使用<pre></pre>，然后html渲染器会将其视为预格式化。您也可以尝试添加</br>\n而不将HTML标记添加到输出行分隔符。我相信Swing需要文本，但希望它是HTML。
