Program to demonstrate how to parse a comma-separated String using String's split method and StringTokenizer class in Java.
package com.hubberspot.examples;
import java.util.StringTokenizer;
public class CommaSeperatedParsing {
public static void main(String[] args) {
// Create a String or pass any String containing comma
// This utility will separate the String using split method.
String commaSeperatedString = "Name = Value,First Name = Jonty," +
"Last Name = Magicman,UserName = Jontymagicman," +
"Email = Jonty@Magic.com" ;
System.out.println("Method 1 : Using String class split() method ... ");
System.out.println();
// String class has a method called as split method
// this method takes in a regular expression and based
// on the expression returns a array containing the
// strings
String[] output = commaSeperatedString.split(",");
// using a for loop to print the parsed string to
// console
for(int i = 0; i < output.length; i++)
{
System.out.println(output[i]);
}
System.out.println();
System.out.println("Method 2 : Using StringTokenizer class ... ");
System.out.println();
// Pass the String to the StringTokenizer class which will
// break it into tokens separated by spaces.
StringTokenizer stringTokenizer =
new StringTokenizer(commaSeperatedString , ",");
// Applying while loop over the condition (till StringTokenizer
// has no more elements left which are seperated by tokens.
while(stringTokenizer.hasMoreElements())
{
// StringTokenizer has nextElement method which gets
// us the next string in the class.
System.out.println(stringTokenizer.nextElement());
}
}
}
