I need to split array of string and then save it into smaller string. Plz help me....what i am doing wrong.....
for(int i=0; i<suburl.size(); i++){
String temp = suburl.get(i);
String[] data = temp.split(" ");
Log.i("DATA 0", data[0]);
Log.i("DATA 1", data[1]);
Log.i("DATA 2", data[2]);
}
here
public static ArrayList<String> suburl = new ArrayList<String>();
where,
suburl.get(0) = "alex 21 engineer"
suburl.get(1) = "mike 22 lawyer"
suburl.get(2) = "sunny 26 deisnger"
suburl.get(3) = "kim 24 painter"
and
String[] data;
But what i am getting error when splitting is .......

What I think is that problably, not all your strings have two spaces. Just do not do things like data[x]. Use another loop to use those strings.
ReplyDeleteThis works for me, I am not sure what's wrong. You can cross check the input data again.
ReplyDeleteList<String> suburl = new ArrayList<String>();
suburl.add("alex 21 engineer");
suburl.add("xyz 21 engineer");
suburl.add("tim 21 engineer");
suburl.add("gary 21 engineer");
for(String temp : suburl) {
String[] data = temp.split(" ");
System.out.println("DATA 0 " + data[0]);
System.out.println("DATA 1 " + data[1]);
System.out.println("DATA 2 " + data[2]);
}
It is working fine for me:
ReplyDeletepublic class TestClass {
public static void main(String args[]) {
ArrayList<String> suburl = new ArrayList<String>();
suburl.add("alex 21 engineer");
suburl.add("xyz 21 engineer");
suburl.add("tim 21 engineer");
suburl.add("gary 21 engineer");
for(int i=0; i<suburl.size(); i++){
String temp = suburl.get(i);
String[] data = temp.split(" ");
System.out.println(data[0]);
System.out.println(data[1]);
System.out.println(data[2]);
}
Results:
alex
21
engineer
xyz
21
engineer
tim
21
engineer
gary
21
engineer
Yuo must replace i<suburl.size(); to i<suburl.size() - 1;
ReplyDeleteIf you set your data in the ArrayList like this:
ReplyDeletesuburl.get(0) = "alex 21 engineer"
suburl.get(1) = "mike 22 lawyer"
suburl.get(2) = "sunny 26 deisnger"
suburl.get(3) = "kim 24 painter"
I think you may want to change it and do suburl.add("alex 21 engineer");
