如何在内容中使用引号拆分String

Question

I have a String which looks like this:

"["xxx","yyy","zzz"]"

Can anyone give me a hint on how to convert it to an array that looks like this:

somestring[0]="xxx"
somestring[1]="yyy"
somestring[2]="zzz"

Answer 1

The expression

"[\"xxx\",\"yyy\",\"zzz\"]".replaceAll( "[\\\"\\[\\]]", "" ).split( "," );

will result in an array:

a[0] = "xxx";
a[1] = "yyy";
a[2] = "zzz";

I hope...

I confirm:

public static void main(String[] args) {
    for( String part : "[\"xxx\",\"yyy\",\"zzz\"]".replaceAll( "[\\\"\\[\\]]", "" ).split( "," )) {
        System.out.println( part );
    }
}

outputs:

xxx
yyy
zzz

Answer 2

Dirty hack

String s1="[\"xxx\",\"yyy\",\"zzz\"]";
        String s2= s1.replaceAll("\"", "" );
        s2=s2.replace("[", "");
        s2=s2.replace("]", "");
        String ar[] =s2.split(",");

Answer 3

Looking at input string pattern, substring will also work:

String inStr = "\"[\"xxx\",\"yyy\",\"zzz\"]\"";
String [] inArray = inStr.substring(0,inStr.length()-2).substring(2).split(",");
System.out.println(Arrays.toString(inArray));

Will print:

    ["xxx", "yyy", "zzz"]

If you wish to remove quotes ("), then write like:

String inStr = "\"[\"xxx\",\"yyy\",\"zzz\"]\"";
String [] inArray1 = inStr.substring(0,inStr1.length()-2)
                          .substring(2).replaceAll("\"","").split(",");
System.out.println(Arrays.toString(inArray1));

Or you can do:

String inStr = "\"[\"xxx\",\"yyy\",\"zzz\"]\"";
String [] inArray = inStr.replaceAll( "[\\\"\\[\\]\"]", "").split( "," );
System.out.println(Arrays.toString(inArray0));

The above two will print:

    [xxx, yyy, zzz]
