在java swing中需要幫助，創建一個簡單的表格

Question

我是java swing的新手。其實我有以下情況：

Case1 : 「the collection was guaranteed.i'm sure it is」 
Case2 : the collection was guaranteed.i'm sure it is 
Case2 : the collection was guaranteed...i'm sure it is 

這些情況下，我想反映使用一個swing window.Which將接受這些情況。

條件：

在case1，因爲文本是由「」它不應該做任何事情包圍。

第二種情況，由於數據沒有被「」包圍，「」。應突出顯示（如果「。」是單個）黃色。

第三種情況正弦「。」之前或之後是另一個「。」它應該保持原樣。

有人建議我這可以使用波動來完成，請給我一個關於如何進行的想法。在這裏，我想要一個表格，我們可以粘貼這個文本和一個名爲「清潔」的按鈕，一旦它被擊中，黃色突出顯示應該出現在這段時間。也請給我建議一些很好的參考波動。

我試過的是如下。這是我不知道如何開始，以及如何沒有多少迴旋的經驗，最簡單的方法是使用HTML進行

Answer 1

沒有完全完成。

使用JTextPane（或JEditorPane）。

textPane.setContentType("text/html"); 

如果代碼設置，確保字符串開頭"<html>"：

textPane.setText("<html>「the collection was guaranteed.i'm sure it is」"); 

現在你可以使用HTML標記，着色，如：

"~~~<span style='background-color:#ffff00'>.</span>~~~" 

的文件變化監聽器或按鍵監聽器可以每次重新添加標記。

Document doc = textPane.getDocument(); 
String plainText = doc.getText(0, doc.getLength()); 

對於可以使用的邏輯正則表達式，i.a.與所謂的前瞻。一個單獨的章節。

Answer 2

我做了一個簡短的例子。

• 使用適當的佈局管理按照您的需求
• 我檢查你的大多數情況下，可能不是所有
• 我使用了一個Highlighter突出「」
