v.addElement("test");
v.addElement("hello");
v.addElement("JAVA");
v.addElement("Program");


Vector<String> v2=new Vector();


for(int I=0 ; I < v.size() ; I++)
{
if( v.elementAt(I).length() < v.elementAt(I + 1).length() ) // checking which element is the longest
{
v2.addElement(v.elementAt(I)); // store them in vector v2
}
}
for(String z : v2)
System.out.println(z);
}
}
