Java code help needed for If-elseif statement

Question

HI All,
Apologies for posting such a trivial thing but I am a novice in Java.
All I need is to code an If elseIF statement.
I tried the code below
String w = "SAPA";
String x = "SAPB";
if (a==w) ;
{Channel channel = LookupService.getChannel("BS_PROD","CC_RFC_LOOKUP");}
else if (a==x)
{ Channel channel = LookupService.getChannel("BS_PROD","CC_RFC_LOOKUP_ECQ"); }
It came back with the error
Source code has syntax error:  D:/usr/sap/XRD/DVEBMGS02/j2ee/cluster/server0/./temp/classpath_resolver/Map695b77619ad011dd8d0b001a4b52813a/source/com/sap/xi/tf/_MM_TRANSMISSION_CHECK_TO_GENIUS_.java:324: 'else' without 'if' else if (a==x) ^ 1 error
Appreciate if you could let me know the correct code.
Many thanks
Shirin

HI Aamir,
After I removed the semi-colon iIt came back with the following error
Source code has syntax error:  D:/usr/sap/XRD/DVEBMGS02/j2ee/cluster/server0/./temp/classpath_resolver/Map1d9b43e09ad111dd84b7001a4b52813a/source/com/sap/xi/tf/_MM_TRANSMISSION_CHECK_TO_GENIUS_.java:328: cannot resolve symbol symbol : variable channel location: class com.sap.xi.tf._MM_TRANSMISSION_CHECK_TO_GENIUS_ accessor = LookupService.getRfcAccessor(channel); ^ 1 error
Just for reference my entire Jave UDF looks like this:
//write your code here
String w = "SAPA";
String x = "SAPB";
  String content = "";
MappingTrace importanttrace;
importanttrace = container.getTrace() ;
//Filling the string with our RFC-XML (With Values)
String m = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><ns0:ZIFMS_GET_NEXT_NUMBER xmlns:ns0=\"urn:sap-com:document:sap:rfc:functions\"><I_NR_RANGE_NR>01</I_NR_RANGE_NR><I_OBJECT>ZIFMS_INT</I_OBJECT></ns0:ZIFMS_GET_NEXT_NUMBER>";
RfcAccessor accessor = null;
ByteArrayOutputStream out = null;
try
//1. Determine a channel (Business System, Communication channel)
if (a==w)
{Channel channel = LookupService.getChannel("BS_PROD","CC_RFC_LOOKUP");}
else if (a==x)
{ Channel channel = LookupService.getChannel("BS_PROD","CC_RFC_LOOKUP_ECQ"); }
//2. Get a RFC accesor for a channel.
accessor = LookupService.getRfcAccessor(channel);
//3. Create a xml input stream representing the FM request message.
InputStream inputstream = new ByteArrayInputStream(m.getBytes());
//4. Create xml Payload
XmlPayload payload = LookupService.getXmlPayload(inputstream);
//5. Execute Lookup
Payload result = accessor.call(payload);
InputStream in = result.getContent();
//This are the extra step which i dont know what it mean
//out = new ByteArrayOutputStream(1024);
//byte[] buffer = new byte1024;
//for (int read = in.read(buffer); read > 0; read = in.read(buffer))
//out.write(buffer,0,read);
//content = out.toString();
try {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(in);
NodeList list = document.getElementsByTagName( "E_NUMBER" );
Node node = list.item(0);
if (node != null)
node = node.getFirstChild();
if (node != null)
content = node.getNodeValue();
} catch (Exception e) {
importanttrace.addWarning("Error while closing accesor" + e.getMessage());
catch (LookupException e)
importanttrace.addWarning("Error While lookup" + e.getMessage());
//This exception is not to be catch at this step as there is no try step before this
//catch (IOException e)
//importanttrace.addWarning("Error" + e.getMessage());
finally
if(out!=null)
try{
out.close();
} catch (IOException e) {
importanttrace.addWarning("Error while closing system" + e.getMessage());
//7. close the accessor in order to free resources
if (accessor!=null) {
try{
accessor.close();
} catch (Exception e) {
importanttrace.addWarning("Error while closing accesor" + e.getMessage());
return content;
