How to extract this string variable in android?

Question

String test=
      [\"1\",\"Low-level programming language\",true],
      [\"2\",\"High level programming language\",false],
      [\"3\",\"Machine language\",false],[\"         


        

Answer 1

You could split on a simple regex:

String [] splitStrings = test.split("\\],\\[");

You don't want to split on just comma because you only want the commas between the square brackets.

Here is a more complete example (and a regex that holds onto the brackets if you want)

public static void main(String []args){
    String test="[\"1\",\"Low-level programming language\",true],[\"2\",\"High level programming language\",false],[\"3\",\"Machine language\",false],[\"4\",\"All of the above\",false],[\"5\",\"None of these\",false]";
    String [] splitStrings = test.split("(?!\\]),(?=\\[)");

    System.out.println(splitStrings[0]);
    System.out.println(splitStrings[1]);
    System.out.println(splitStrings[2]);
    System.out.println(splitStrings[3]);
    System.out.println(splitStrings[4]);
}
