package com.myjava.ip;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class MyIpByHost {

    public static void main(String a[]){
    
        try {
            InetAddress host = InetAddress.getByName("www.java2novice.com");
            System.out.println(host.getHostAddress());
        } catch (UnknownHostException ex) {

Preemptive scheduling Vs Time slicing?
Preemptive scheduling: The highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence.

Time slicing: A task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based on priority and other factors.
