You need to write a code segment that transfers the contents of a byte array named dataToSend by using a NetworkStream object named netStream. You need to use a cache of size 8,192 bytes. Which code segment should you use?()
public class Transfers { public static void main(String[] args) throws Exception { Record r1 = new Record(); Record r2 = new Record(); doTransfer(r1, r2, 5); doTransfer(r2, r1, 2); doTransfer(r1, r2, 1); // print the result System.out.println(”rl = “ + r1.get() +“, r2=” + r2.get()); } private static void doTransfer( final Record a, final Record b, final int amount) { Thread t = new Thread() { public void run() { new Clerk().transfer(a, b, amount); } }; t.start(); } } class Clerk { public synchronized void transfer(Record a, Record b, int amount){ synchronized (a) { synchronized (b) { a.add(-amount); b.add(amount); } } } } class Record { int num=10; public int get() { return num; } public void add(int n) { num = num + n; } } If Transfers.main() is run, which three are true?()
You need to write a code segment that transfers the first 80 bytes from a stream variable named stream1 into a new byte array named byteArray. You also need to ensure that the code segment assigns the number of bytes that are transferred to an integer variable named bytesTransferred. Which code segment should you use?()
