如何刪除字符串中的特殊字符

Question

例如，我想從我的字符串中刪除"[", "]" ， "," ，

[569.24, 569.24, 568.10, 566.00, 566.01, 566.00, 567.98, 565.14]

至

569.24 569.24 568.10 566.00 566.01 566.00 567.98 565.14

但是，我可以刪除","但可以刪除"," "["和"]"

我的代碼如下。

String content = price_result.toString();           
//remove special characters
String content_modified = content.replaceAll("[ \t\"',;]+", " ");
System.out.println(content_modified);

以上結果為[569.24, 569.24, 568.10, 566.00, 566.01, 566.00, 567.98, 565.14] ..

如何刪除"["和"]" ？

Answer 1

只是用這個

String content = price_result.toString();           
//remove special characters
String content_modified = content.replace("[","").replace("]","").replace(",","");
System.out.println(content_modified);

Answer 2

您可以嘗試下一個：

// Characters you want to remove
String unwanted = "[],";

// It will be used frequently? Use a constant.
Pattern pattern = Pattern.compile("[" + Pattern.quote(unwanted) + "]");

String content = price_result.toString();
String content_modified = pattern.matcher(content).replaceAll("");
System.out.println(content_modified);

Answer 3

將它們放在轉義字符\\中的字符類[]

String content_modified = content.replaceAll("[\\[\t\"',;\\]]+", " ");

或者一個接一個地傳送它們（自己輸入其他字符：）

String content_modified = content.replaceAll("\\[|\\]|,|;", " ");
