Conversion of a Java string to a string array

When working with a CSV file, it is often necessary to convert the string to a string array, or to a string array.

In the evening, we studied the string correlation function, which can be implemented by the split function and the join function.

As follows:

 Public classtestlist { Public Static voidMain (string[] args) {//TODO auto-generated Method StubString s = "A."; //string to string array using the Split functionString[] S_array=s.split (",");  for(String string:s_array) {System.out.println (string); } s_array[0]= "234"; String Delimetal=","; //string array to string with String.Join functionSystem.out.println (String.Join (Delimetal, S_array)); }}
