How to execute the program to display MIB node information using com.adventnet.snmp.mibs package

The code is as follows to find MIB node infomation

Code :

import com.adventnet.snmp.snmp2.*;
import com.adventnet.snmp.mibs.*;
import java.io.*;
 
public class MibNodeInfo {
 
public static void main(String args[]) {
 
            if( args.length < 2)
	{
		System.out.println("Usage : java MibNodeInfo mibfile OID ");
//		System.exit(0);
	}
 
	// Take care of getting OID and the MIB file name
 
	    String mibfile ="RFC1213-MIB";
	    String OID = "10.3.2.120 1.2.0";       
 
	// load the MIB file 
	MibOperations mibops = new MibOperations();
	try {
 
	mibops.loadMibModules(new File(mibfile));
//	mibops.loadMibModules(mibfile);
	} catch (Exception ex){
	     System.err.println("Error loading MIBs: "+ex.getMessage());
	}
 
 
	// add OIDs
 
	 SnmpOID oid = mibops.getSnmpOID(OID);
	 MibNode node = mibops.getMibNode(oid);
 
	if(node == null) 
	        {
			System.out.println("Invalid OID / the node " + oid + " is not available");
		}
	else 
	    {
 
		System.out.println("Syntax:"+node.getSyntax()+"/n"+
                   "Access:"+node.printAccess()+"/n"+
                   "Status:"+node.getStatus()+"/n"+
                   "Reference:"+node.getReference()+"/n"+
                   "OID:"+node.getNumberedOIDString()+"/n"+
                   "Node:"+node.getOIDString()+"/n"+
                   "Description:"+node.getDescription()+"/n");
	    }
 
 }
