Explain input buffering in detail
WebInput/output (I/O) buffering is a mechanism that improves the throughput of input and output operations.

Web( See Figure 13.10 below. ) A slow device may write data into a buffer, and when the buffer is full, the entire buffer is sent to the fast device all at once. So that the slow device still has somewhere to write while this is going on, a second buffer is used, and the two buffers alternate as each becomes full. This is known as double buffering. WebApr 3, 2024 · The capacity () method of StringBuffer class returns the current capacity of the buffer. The default capacity of the buffer is 16. If the number of characters increases from its current capacity, it increases the capacity by (oldcapacity*2)+2. For instance, if your current capacity is 16, it will be (16*2)+2=34. Example:
