Thread: 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);

please help me guys :S

thx a lot.

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);
}
