Java StringTokenizer Example

In Java, you can use the Stringtokennizer class to split a String into the different tokenas by defined delimiter. (Space is the default delimiter). Here ' re the StringTokennizer examples:

Example 1

Uses StringTokennizer to split a string by "space" and "comma" delimiter, and iterate the StringTokenizer elements and print it out O Ne by one.

 PackageCom.mkyong;ImportJava.util.StringTokenizer; Public classApp { Public Static voidMain (string[] args) {String str= "This is a String, split by StringTokenizer, created by Mkyong"; StringTokenizer St=NewStringTokenizer (str); System.out.println ("----Split by Space------");  while(St.hasmoreelements ()) {System.out.println (st.nextelement ()); } System.out.println ("----Split by comma ', '------"); StringTokenizer St2=NewStringTokenizer (str, ",");  while(St2.hasmoreelements ()) {System.out.println (st2.nextelement ()); }    }}

Output

----Split by space------Thisisstring,splitbystringtokenizer,createdbymkyong----split by comma ', '------ This is a String  split by StringTokenizer created by Mkyong

Example 2

Read a CSV file and use StringTokenizer to split the string by ' | ' delimiter, and print it out.

File:c:/test.csv

 PackageCom.mkyong;ImportJava.io.BufferedReader;ImportJava.io.FileReader;Importjava.io.IOException;ImportJava.util.StringTokenizer; Public classReadFile { Public Static voidMain (string[] args) {bufferedreader br=NULL; Try{String line; BR=NewBufferedReader (NewFileReader ("Test.csv"));  while(line = Br.readline ())! =NULL) {System.out.println (line); StringTokenizer StringTokenizer=NewStringTokenizer (line, "|");  while(Stringtokenizer.hasmoreelements ()) {Integer ID=Integer.parseint (Stringtokenizer.nextelement (). toString ()); Double Price=double.parsedouble (Stringtokenizer.nextelement (). toString ()); String username=stringtokenizer.nextelement (). toString (); StringBuilder SB=NewStringBuilder (); Sb.append ("\nid:" +ID); Sb.append ("\nprice:" +Price ); Sb.append ("\nusername:" +username); Sb.append ("\n*******************\n");           System.out.println (Sb.tostring ()); }} System.out.println ("Done"); } Catch(IOException e) {e.printstacktrace (); } finally {        Try {            if(BR! =NULL) Br.close (); } Catch(IOException ex) {ex.printstacktrace (); }    }     }}

Output
