comma separated into string array
|
Question: How can I get substrings from comma separated string?
Example: Comma separated into string array operation can be done like this
private String[] commaSeparatedStringToStringArray(String
aString){
String[] splittArray = null;
if (aString != null ||
!aString.equalsIgnoreCase("")){
splittArray =
aString.split(",");
System.out.println(aString +
" " + splittArray);
}
return splittArray;
}
Then easily you find array size and loop it to get elements separately
