Split strings keeping all trailing empty elements

Question

I am relatively new to java programming. How would you split following lines of Strings separated by semicolons?

String; String; String; String, String; String;;         


        

Answer 1

Since you stated that you want to contain the spaces, only split on the ; and want to keep 8 arguments for your constructor, we are going to use the split with a limit method.

String.split(String,int)

Example:

String in = "String; String; String; String, String; String;;String;";
String[] s1 = in.split(";");

Gives:

["String"," String"," String, String"," String"," String","","String"]

What is only 7 in length and will fail your constructor.

String[] s = in.split(";",8);

Gives:

["String"," String"," String"," String, String"," String","","String",""]`

What is 8 in length and will work.

You can then address your constructor using:

YourObject obj = new YourObject(s[0],s[1],s[2],s[3],s[4],s[5],s[6],s[7]);
