String Tokenizer in Java…

Example : STDemo

import java.util.StringTokenizer;
class STDemo
{
static String in ="title=java:The Complete Reference;"+"author=Schildt;"+
"Publisher=Osborne/McGraw-Hill;"+
"copyright=2002";
public static void main(String args[])
{
StringTokenizer st=new StringTokenizer(in,"=;");
while(st.hasMoreTokens())
{
String key=st.nextToken();
String val=st.nextToken();
System.out.println(key+"\t"+val);
}
}
}

Vector in Java…

Example : VectorDemo

import java.util.*;
import java.io.*;
class VectorDemo
{
	public static void main(String args[])
	{
		Vector<String> list=new Vector<String> ();
		list.add("software");
		list.add("testing");
		list.add("program");
		list.add("class");
		list.insertElementAt("JAVA",2);
		list.removeElementAt(3);
		//list.removeAllElement();
		//list.removeElement("c");
		int size=list.size();
		String l[]=new String[size];
		list.copyInto(l);
		System.out.println("List of Languages");
		for(int i=0;i<size;i++)
		{
			System.out.println(l[i]);
		}
	}
}
