    Default Help to translate from C to java

    hello guys,

    i am trying to translate a little code from C to java, but i cant..

    please help me..


    the first part is:
    struct tPacket
    {
    	WORD size;
    	WORD opcode;
    	BYTE securityCount;
    	BYTE securityCRC;
    	BYTE data[8186];
    };     // A genrel Packet
     
    struct tPacket_5000_E
    {
    	WORD size;
    	WORD opcode;
    	BYTE securityCount;
    	BYTE securityCRC;
    	BYTE flag;
    	BYTE blowfish[8];
    	DWORD seedCount;
    	DWORD seedCRC;
    	DWORD seedSecurity[5];
    };    
     
    struct tPacket_5000_10
    {
    	WORD size;
    	WORD opcode;
    	BYTE securityCount;
    	BYTE securityCRC;
    	BYTE flag;
    	DWORD challenge[2];
    };
    and the second part is :
    int rcv = 0;
    tPacket Packet;
     
    do
    {
          recv(Socket, (char *)Packet, sizeof(Packet), 0);
          if (rcv > 0)
          {
                 if (Packet.opcode == 0x5000 && Packet.size == 0x25)
                       std::cout << "First Packet received";
                 else if (Packet.opcode == 0x5000 && Packet.size == 0x09)
                       std::cout << "Second Packet received";
                 else if (Packet.opcode != 0x5000)
                 {
                       pritnf("%.4X %.4X %.2X %.2X", Packet.size, Packet.opcode, Packet.securityCount, Packet.securityCRC);
                       for(int i = 0; i < Packet.size; i++)
                       {
                             printf("%.2X", Packet.data[i]);
                       }
                 }
    }
    while(rcv != SOCKET_ERROR);

    Hi dear, this could approx be like this-

    public class tPacket
    {
    public short size;
    public short opcode;
    public byte securityCount;
    public byte securityCRC;
    public String data = new String(new char[8186]);
    } // A genrel Packet
     
    public class tPacket_5000_10
    {
    public short size;
    public short opcode;
    public byte securityCount;
    public byte securityCRC;
    public byte flag;
    public int[] challenge = new int[2];
    }
     
    public class tPacket_5000_E
    {
    public short size;
    public short opcode;
    public byte securityCount;
    public byte securityCRC;
    public byte flag;
    public String blowfish = new String(new char[8]);
    public int seedCount;
    public int seedCRC;
    public int[] seedSecurity = new int[5];
    }
     
    public class GlobalMembersB
    {
     
     
    	public static int rcv = 0;
    	public static tPacket Packet = new tPacket();
     
    	do
    	{
    //C++ TO JAVA CONVERTER TODO TASK: There is no Java equivalent to 'sizeof':
    	recv(Socket, (String)Packet, sizeof(Packet), 0);
    	if (rcv > 0)
    	{
    	if (Packet.opcode == 0x5000 && Packet.size == 0x25)
    	{
    	System.out.print("First Packet received");
    	}
    	else if (Packet.opcode == 0x5000 && Packet.size == 0x09)
    	{
    	System.out.print("Second Packet received");
    	}
    	else if (Packet.opcode != 0x5000)
    	{
    	pritnf("%.4X %.4X %.2X %.2X", Packet.size, Packet.opcode, Packet.securityCount, Packet.securityCRC);
    	for(int i = 0; i < Packet.size; i++)
    	{
    	System.out.printf("%.2X", Packet.data.charAt(i));
    	}
    	}
    	}
    	while(rcv != SOCKET_ERROR);
    }
