Im a new learner of java. This example of switch case helped me to understand the syntax clearly. The program also provided more knowledge. I will visit this site whenever i get doubt.Thanks. Good work.

import java.io.*;

public class SvowelDPS
{
public static void main(String args[]) throws Exception
{
DatagramSocket ds=new DatagramSocket(40000);
byte rb[]=new byte[100];
System.out.println("Connection");

DatagramPacket dp=new DatagramPacket(rb,rb.length);
ds.receive(dp);
System.out.println("Receive Data:"+new String(dp.getData()));
String str=new String(dp.getData());
String res="";
str=str.trim();
switch(str) //error on this point.How can i do?
{
case "a":
res=("Vowel");
break;
case "A":
res=("Vowel");
break;
case "e":
res=("Vowel");
break;
case "E":
res=("Vowel");
break;
case "i":
res=("Vowel");
break;
case "I":
res=("Vowel");
break;
case "o":
res=("Vowel");
break;
case "O":
res=("Vowel");
break;
case "U":
res=("Vowel");
break;
case "o":
res=("Vowel");
break;
default:
res=("Not Vowel");
break;
}

InetAddress cipadd=dp.getAddress();
int cport=dp.getPort();
byte sb[]=new byte[100];
sb=res.getBytes();
DatagramPacket dpsend=new DatagramPacket(sb,sb.length,cipadd,cport);
ds.send(dpsend);
System.out.println("Data send") ;
}


}

You cannot use strings on Swithc, you can only use int. So, it would be a better idea to capture the lettes ascii code and evaluate your switch accordingly.

since you are using characters try using ' ' (Single quotes) instead of using " " double quotes
