Split a field through array in java

I would like to know how to split a field through array using Java. For example we have GLaccount like AAAA-BBBB-CCCC and we would like to split each component and store it in an variable however the GLaccount may have AAAA-BBBB (no third component) so in this case variable segment3 throws NULL POINTER exception so I am not sure on how to fix this since I am new to Java. 

String GL = getOwner().getGL("GLACCT");
String segment1 = GL.split("-")[0];
String segment2 = GL.split("-")[1];
String segment3 = GL.split("-")[2];

import java.util.Arrays;    
List<String> list = Arrays.asList(GL.split("-"));

With this code you do not need to think if you have 2,3 or 10 strings, and to add new if for every new one.

Use split method (once) and check returned array length :

 String[] values3 = "AAAA-BBBB-CCCC".split("-");
 // values.length == 3 


 String[] values2 = "AAAA-BBBB".split("-");
 // values2.length == 2

Using split("-" ) will give you an array of strings. before using array value, you can check the size of array that if it contains enough elements to use.. 

String GL = getOwner().getGL("GLACCT"); 
String[] array=GL.split("-");
String segment1 = array[0]; 
String segment2 = array[1]; 

//check if array have 3rd element 
if(array.length >2)
      String segment3 = array[2];
else
       System.out.println("No third element") ;
