String to String Array Android project

Question

On developing an Android project I have got stacked in position

I don't want to describe because it is simple.

String str = "Physics,Chemistry,Biology"

This is my String and three queries are divided by comma. One of my method returns string like this.

So I want to make it to a string array. This will like that dividing comma based.

String[] strArr = {"Physics", "Chemistry", "Biology"};

[`String.split`](https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#split(java.lang.String)) ? — Michael, Jan 07 '18 at 17:50

there is a method in String class that can help you convert it, but you should give this method the regex , in your case regex is ","

you can use this method to convert it:

   public String[] convertToArray(String str, String regex){
    return str.split(regex);
   }

   String[] str = convertToArray(str, ",");
