how get current CPU temperature programmatically in all Android Versions?

I am using this code for get current CPU Temperature :
and saw it too
private float getCurrentCPUTemperature() {
String file = readFile("/sys/devices/virtual/thermal/thermal_zone0/temp", '\n');
if (file != null) {
return Long.parseLong(file);
} else {
return Long.parseLong(batteryTemp + " " + (char) 0x00B0 + "C");
}
}
private byte[] mBuffer = new byte[4096];
#SuppressLint("NewApi")
private String readFile(String file, char endChar) {
// Permit disk reads here, as /proc/meminfo isn't really "on
// disk" and should be fast. TODO: make BlockGuard ignore
// /proc/ and /sys/ files perhaps?
StrictMode.ThreadPolicy savedPolicy = StrictMode.allowThreadDiskReads();
FileInputStream is = null;
try {
is = new FileInputStream(file);
int len = is.read(mBuffer);
is.close();
if (len > 0) {
int i;
for (i = 0; i < len; i++) {
if (mBuffer[i] == endChar) {
break;
}
}
return new String(mBuffer, 0, i);
}
} catch (java.io.FileNotFoundException e) {
} catch (java.io.IOException e) {
} finally {
if (is != null) {
try {
is.close();
} catch (java.io.IOException e) {
}
}
StrictMode.setThreadPolicy(savedPolicy);
}
return null;
}
and use it like it :
float cpu_temp = getCurrentCPUTemperature();
txtCpuTemp.setText(cpu_temp + " " + (char) 0x00B0 + "C");
it is work like a charm but for android M and under. For Android N and above (7,8,9) Do not Work and Show The Temp like this :
57.0 in android 6 and under (6,5,4)
57000.0 in android 7 and above (7,8,9)
I try this code too :
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {
txtCpuTemp.setText((cpu_temp / 1000) + " " + (char) 0x00B0 + "C");
}
but do not work :(
How can I get the Temp in all android versions??
UPDATE:
I change The code like it and work on some devices
Except Samsung:
float cpu_temp = getCurrentCPUTemperature();
txtCpuTemp.setText(cpu_temp + " " + (char) 0x00B0 + "C");
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {
txtCpuTemp.setText(cpu_temp / 1000 + " " + (char) 0x00B0 + "C");
}

Divide the value by 1000 on newer API:
float cpu_temp = getCurrentCPUTemperature();
if(Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {
cpu_temp = cpu_temp / 1000;
}
I'd just wonder where batteryTemp comes from and how it should be related to the CPU.

DatagramPacket is accumulating values

I created a chat in Java, which displays the messages sent and received on the screen. The problem is that when sending the message it is picking up the previously sent value. For example, I send the message written "Microsoft", and then I send another message written "Apple", when the display shows "Applesoft", it appears that it is not emptying DatagramPacket. What can be done?
class Recebe implements Runnable {
#Override
public void run() {
byte[] dadosReceber = new byte[255];
boolean erro = false;
DatagramSocket socket = null;
while (true) {
try {
socket = new DatagramSocket(getPorta());
} catch (SocketException ex) {
Logger.getLogger(Conexao.class.getName()).log(Level.SEVERE, null, ex);
}
erro = false;
while (!erro) {
DatagramPacket pacoteRecebido = new DatagramPacket(dadosReceber, dadosReceber.length);
try {
socket.receive(pacoteRecebido);
byte[] b = pacoteRecebido.getData();
String s = "";
for (int i = 0; i < b.length; i++) {
if (b[i] != 0) {
s += (char) b[i];
System.out.println("Valor S: " + s + " ");
}
}
// if (!s.equals(new GeraHash().MD5("envie a chave publica!!!"))) {
String nome = pacoteRecebido.getAddress().toString() + " disse:";
notifica(nome + s);
System.out.println("Dados Recebe 2: " + s + " ");
// } else {
// conexaoAtual().envia("Funcionou!");
// System.out.println("Dados Recebe 1: " + s + " ");
// }
} catch (Exception e) {
System.out.println("erro");
try {
Thread.sleep(100);
} catch (InterruptedException ex) {
Logger.getLogger(Conexao.class.getName()).log(Level.SEVERE, null, ex);
}
erro = true;
continue;
}
}
}
}
}

socket.receive(pacoteRecebido);
byte[] b = pacoteRecebido.getData();
String s = "";
for (int i = 0; i < b.length; i++) {
if (b[i] != 0) {
s += (char) b[i];
System.out.println("Valor S: " + s + " ");
}
Usual problem. You're ignoring the actual length of the received datagram, given by DatagramPacket.getLength(). You can reduce all that to:
socket.receive(pacoteRecebido);
System.out.println(new String(pacoteRecebido.getData(), 0, pacoteRecebido.getLength());

This is some alternate code that's much shorter and gets the same errors:

You're not setting the CLASSPATH when you're running the program so it's not finding the javax.mail.jar file:

write a program in java using modbus simulator for reading holding register values

I want to take real-time data using modbus tcp/ip simulator for filling of a tank that uses port no 502.
How can I write a code in java to get the holding register value from the simulator and also I want to control the values of it?

If you use a Modbus library like this one most of the work is already done for you.
ModbusTcpMasterConfig config = new ModbusTcpMasterConfig.Builder("localhost").build();
ModbusTcpMaster master = new ModbusTcpMaster(config);
CompletableFuture<ReadHoldingRegistersResponse> future =
master.sendRequest(new ReadHoldingRegistersRequest(0, 10), 0);
future.thenAccept(response -> {
System.out.println("Response: " + ByteBufUtil.hexDump(response.getRegisters()));
ReferenceCountUtil.release(response);
});

Reading data from a device connected to usb port

I have to read data(signals) from a device which sends signals continously to USB port and display it on monitor.
As POC I tried reading data from USB flash drive connected to my system. I am using JUSB library for windows. But, as I change ,my device driver settings as described in below doc for JUSB, my device configurations disappear( I get null for device.getConfiguration();).
http://www.steelbrothers.ch/jusb/ -- documents-->appendix D
Can anyone please help me to figure out where I am going wrong or suggest me some other good API to read data from USB device using JAVA.
Code is below,
try{
Device device = null;
DeviceImpl dev;
for(int k=0; k < busses.length ; k++){
System.out.println("\n\nBus[ " + ((USB)busses[k]).getBusNum() + " ] ");
