VECTOR IN JAVA WITH SOME METHODS

Vector only support Literal datatype value not support primitive datatype.
This program describes some method in Vector class.

import java.io.*;
import java.util.*;
class sample vectors
{
public static void main(String arg[])
{
    Vector v=new Vector();
    System.out.println("size : "+v.size());
    System.out.println("capacity : "+v.capacity());
    String a,b,c,d;
    a="RAMAN";
    b="seetha";
    c="MURUGAN";
    d="valli";
v.addElement(a);
v.addElement(b);
v.addElement(c);
v.addElement(d);
v.addElement(a);
v.addElement(b);
v.addElement(c);
v.addElement(d);

System.out.println("size : "+v.size());
System.out.println("capacity : "+v.capacity());
System.out.println(v);
System.out.println("first element:"+v.firstElement());
System.out.println("last element:"+v.lastElement());
System.out.println(v.get(3));

v.insertElementAt("balaji",2);
System.out.println(v);
v.setElementAt("RAVIVARMAN",3);
System.out.println(v);

v.removeElementAt(2);
System.out.println(v);

v.removeAllElements();
System.out.println(v);
System.out.println("size : "+v.size());
System.out.println("capacity : "+v.capacity());

}
}

Interface with extends

Interface class =========== an interface class extends with another interface class and implements with a class. example code shown below. import java.io.*; interface interone {     public void addition() throws IOException; } interface intertwo {     public void subtraction() throws IOException; } interface interthree extends intertwo            // An interface class can be extended to another interface class {       public void multiplication() throws IOException; } class exampleclass1 implements interone,interthree    {   DataInputStream ds=new DataInputStream(System.in);     int a,b,c;     public void addition() throws IOException     {             System.out.println("Enter two values for Addition");             a=Integer.parseInt(ds.readLine());             b=Integer.parseInt(ds.readLi...

Abstract and Final Class sample

Abstract Class: =========== We cannot create object directly of abstract class, we must inherit the abstract class into another class, interface, then we can use the method  contain in abstract class. Another important condition we must use the method of abstract class in derived place.   import java.io.*; abstract class pnr {     public void pnr_calculate() throws IOException     {             int principle,num_month;             float rate_interest,si;             DataInputStream ds=new DataInputStream(System.in);             System.out.println("Enter Principle Amount");              principle=Integer.parseInt(ds.readLine());              System.out.println("Enter duration in Months");               num_m...
