How to convert string into boolean array?

Question

I convert everything in my Android app into string and add it to a Sqlite database. I use the code below to convert boolean arrays into string, but I dont know how to convert it back from string into boolean array. There spaces between each true and false in the string. How can I break string at each space into a boolean array?

String work= "";
for (int i = 0;i<go.length; i++) {
    work= work+go[i];
    // Do not append comma at the end of last element
    if(i<go.length - 1){
        work = work+" ";
    }
}

Split the string on your separator character (" ")
Create an array of booleans with the same length of the splitted array of strings
Parse one by one them using Boolean.parseBoolean method

Example:

public static void main(String[] args) {

    String str = "true false true false false";

    String[] parts = str.split(" ");

    boolean[] array = new boolean[parts.length];
    for (int i = 0; i < parts.length; i++)
        array[i] = Boolean.parseBoolean(parts[i]);

    System.out.println(Arrays.toString(array));
}

Outputs:

[true, false, true, false, false]

Please use boolean b = Boolean.parseBoolean(string);
