convert an array to a string in java

  String[] array = {"This", "is", "an", "array"};
  String result = String.join(" ", array);

This code takes an array of strings and turns it into a single string. The code creates an array called “array” and assigns it a set of strings. It then uses the String.join method to convert the array into a single string, with each array element separated by a space character. The result is stored in a String called “result”. The String.join method takes two arguments: the separator (in this case a space character) and the array which is to be converted into a string.
