catch without try

30 Days Ago

Can anyone shed some light on these errors?

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
public void FaultHandler () {
		int faultCount = 0;
	 while ( faultCount < 4 ) {
		  DatagramPacket request =
			  new DatagramPacket(requestArray, requestArray.length, aHost, proxyPort);	
		  aSocket.send(request);	
	 try {
		  aSocket.setSoTimeout(4000);
		  aSocket.receive(reply);
	      }
	 catch ( SocketTimeoutException e ) {
		  faultCount++;
		  continue; 
	      }
	 catch ( IOException e ){}
		 break;
 
	 catch ( IOException e ) {}	  //----it doesn't like this line!
	      if ( faultCount >= 3 )
	      System.exit(0);
	      }
	}
public void FaultHandler () {
		int faultCount = 0;
	 while ( faultCount < 4 ) {
		  DatagramPacket request =
			  new DatagramPacket(requestArray, requestArray.length, aHost, proxyPort);	
		  aSocket.send(request);	
	 try {
		  aSocket.setSoTimeout(4000);
		  aSocket.receive(reply);
	      }
	 catch ( SocketTimeoutException e ) {
		  faultCount++;
		  continue; 
	      }
	 catch ( IOException e ){}
		 break;
	      
	 catch ( IOException e ) {}	  //----it doesn't like this line!
	      if ( faultCount >= 3 )
	      System.exit(0);
	      }
	}

I keep getting these errors:

'catch' without 'try'
catch ( IOException e ) {}
^
Ex2Client.java:18: ')' expected
catch ( IOException e ) {}
^
Ex2Client.java:18: not a statement
catch ( IOException e ) {}
^
Ex2Client.java:18: ';' expected
catch ( IOException e ) {}

Walk through and match up your braces.

The "break" on line 16 is outside any catch, so it terminates the list of catches associated with the previous try. So the catch on line 18 hasn't got a try to match to.

In addition to the "break" comment above, which is dead-on, you also can't catch the same exception twice in a try clause...you're catching IOException a second time after the break.
