Why can't I write ch=ch+1; instead of ch++; though they have same meaning

like below fixes the issue , You need to provide a cast in order to do that :
code :
ch = (char) (ch + 1);

I wish this help you The value is formatted as a hexadecimal integer with four digits and leading zeros. Java uses the same format string syntax. You can find it in the javaDoc of Formatter.
Excerpt:
code :
'x', 'X'     integral    The result is formatted as a hexadecimal integer
// create a String with the formatted value.
String formatted = String.format("%04X ", image[y*width+x]);

// write a formatted value to the console (*)
System.out.printf("%04X ", image[y*width+x]);

Hope this helps DatagramChannel is part of java.nio package. It will take a parameter as ByteBuffer to send to the connected channel. Before trying to send you should connect using InetSocketAddress, which takes the host ip and port as parameter. connect(SocketAddress remote) --> connects the channel to the underlying socket. you can get the socket from Datagramchannel because channel is non blocking io used for read/write purpose. socket peer's is nothing but the remote machine.

wish helps you As long as you are uncomfortable with VB.NET syntax, I would strongly recommend you use Option Strict On so you catch mistakes like these quicker. The best way is by changing it globally so it is always on by default. Tools + Options, Projects and Solutions, VB Defaults, change Option Strict to "On".

around this issue Possibly it is how the library signals fatal errors - by crashing intentionally. Or, possibly, the zeroes are a placeholder for a relocatable address and are supposed to be patched by the loader. Try disassembling with relocation info:

hop of those help? IB write, short for inbound write, is the number of bytes that the PCIe device (specified in the first column) requested to write to main memory through DMA. IB read is the number of bytes that the PCIe device requested to read from main memory through DMA(“Direct Memory Access”). Whether it's a read or write request, it's the device that is issuing the request to the socket (the IIO stack to which the device is connected, to be specific). So it's inbound traffic from the perspective of the socket.
These metrics are measured using the DATA_REQ_OF_CPU uncore event. In particular, the event with umask 0x1 represents a 4-byte inbound write request and the event with umask 0x4 represents a 4-byte inbound read request.
