convert a string to an array in java
Code snippet on how to convert a string to an array in java
String[] arr = str.split(",");
This code uses the split() method to convert a string to an array. The split() method takes a delimiter (in this case, a comma) as an argument, and creates an array with each element being a substring that’s separated by the delimiter. The str variable is a string that we want to convert to an array, and the array is saved to the arr variable. Each substring in the array is separated by the delimiter (comma in this example). For example, if str was “hello,world”, the resulting array would be [“hello”, “world”].
