Find IP address And garbage Collection

For Grabage Collection:-

/** * */ package com.developerstechpoint; import static java.lang.System.*; /** * @author jeetendra * */ public class GarbageCollectionProgram { /** * @param args */ /* * This program performs garbage collection. * Free memory in java virtual machine is printed * and then garbage collection is done using gc method * of RunTime class, freeMemory method returns amount * of free memory in jvm, getRunTime method is used to get * reference of current RunTime object. */ public static void main(String s[]) throws Exception { Runtime rs = Runtime.getRuntime(); out.println("Free memory in JVM before Garbage Collection = "+rs.freeMemory()); rs.gc(); out.println("Free memory in JVM after Garbage Collection = "+rs.freeMemory()); }}

For IP Address:-

/** * */ package com.developerstechpoint; import java.net.InetAddress; import java.net.UnknownHostException; /** * @author jeetendra * */ public class GettingIPofMachine { /** * @param args * @throws UnknownHostException */ /* * This program prints IP or internet * protocol address of your computer system. * InetAddress class of java.net package is used, * getLocalHost method returns InetAddress object which represents local host. */ public static void main(String[] args) throws UnknownHostException { InetAddress inetaddress = InetAddress.getLocalHost(); System.out.println("LocalHost is : "+inetaddress); } }
