I want to convert a String Array to String so that later on while retrieving I can parse String to String[] with the help of (,) separator.
String [] ------------> String
//and later
String ---------------> String[]
Can someone guide on how to do this?
for (int i = 0; i <= count; i++) {
Log.d(TAG, "arrayData == " +arrayData[i]);
// Joining:
String joined = String.join(",", arrayData);
//This will give error "The method join(String, String[]) is undefined for the type String"
}
You can use String.joinStringBuilder and String.split:
// Joining:String joined = String.join(",", stringArr);StringBuilder buffer = new StringBuilder(); for (String each : stringArr) buffer.append(",").append(each); String joined = buffer.deleteCharAt(0).toString(); // Splitting: String[] splitted = joined.split(",");
