Flow control is a technique that allows two stations working at different speeds to communicate with each other. It is a set of measures taken to regulate the amount of data that a sender sends so that a fast sender does not overwhelm a slow receiver.In data link layer, the ... Read More

To create a StringBuffer Object, we use the following syntax −StringBuffer s=new StringBuffer();When we create a reference to an object, we use the assignment operator. For example, String s1 = ”hi”; String s2 = s1; // s2 is a reference of s1A program to illustrate the creation of a StringBuffer ... Read More

Convolutional CodesConvolutional codes are error correcting codes where the data streams of indefinite lengths are encoded before transmission over noisy channels. The message streams are encoded by the sliding application of Boolean functions that generate a sequence of output bits.Convolutional codes were first introduced in 1955, by Elias. After that, ...

Hamming code is a block code that is capable of detecting up to two simultaneous bit errors and correcting single-bit errors. It was developed by R.W. Hamming for error correction.In this coding method, the source encodes the message by inserting redundant bits within the message. These redundant bits are extra ... Read More

Serialization is the process of changing the state of an object into the byte stream so that the byte stream can return back into a copy of the objectIn Java, an object is said to be serializable if its class or parent classes implement either the Serializable interface or the ... Read More

In order to change the default capacity of the StringBuffer Object, we use the ensureCapacity() method. When the current capacity is less than the parameter passed, then a new internal array is allocated with greater capacity.The new capacity is the larger of the minimumCapacity argument and twice the old capacity, ...

In order to remove a character from a Java StringBuffer object, we use the deleteCharAt() method. The deleteCharAt() removes the character at the specified index. The length of resultant sequence of characters of the StringBuffer object is reduced by one.Declaration − The java.lang.StringBuffer.deleteCharAt() method is declared as follows−public StringBuffer deleteCharAt(int ...
