删除Java中的花括号

Question

{aaa,":"bbb,ID":"ccc,}  
{zzz,":"sss,ID":"fff,}  
{ggg,":"hhh,ID":"kkk,} ...  

String s = "{aaa,":"bbb,ID":"ccc,}";
String n = s.replaceAll("{", " ");  

String n = s.replaceAll("/{", " "); 
String n = s.replaceAll("'{'", " "); 

Answer 1

不能像这样定义字符串：

String s = "{aaa,":"bbb,ID":"ccc,}";

错误就在这里，您必须转义字符串中的双引号，如下所示：

String s = "{aaa,\":\"bbb,ID\":\"ccc,}";

现在如果您调用

s.replaceAll("\\{", " ");

String firstPiece = "This is a ";
// this is ok:
String all = s + "String";
//if you call:
System.out.println(all);
//the output will be: This is a String

// this is not ok:
String allWrong = s "String";
//Even if you are putting one after the other the two strings, this is forbidden and is a Syntax error.
