The java.util.InputStream class is the superclass of all classes representing an input stream of bytes.Applications that need to define a subclass of InputStream must always provide a method that returns the next byte of input.
类声明
以下是声明java.util.InputStream class:
public abstract class InputStream
extends Object
implements Closeable

类方法
| S.N. | 方法 & 描述 |
|---|---|
| 1 | int available() This method eturns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. |
| 2 | void close() This method closes this input stream and releases any system resources associated with the stream. |
| 3 | void mark(int readlimit) This method marks the current position in this input stream. |
| 4 | boolean markSupported() This method tests if this input stream supports the mark and reset methods. |
| 5 | abstract int read() This method reads the next byte of data from the input stream. |
| 6 | int read(byte[] b) This method reads some number of bytes from the input stream and stores them into the buffer array b. |
| 7 | int read(byte[] b, int off, int len) This method reads up to len bytes of data from the input stream into an array of bytes. |
| 8 | void reset() This method repositions this stream to the position at the time the mark method was last called on this input stream. |
| 9 | long skip(long n) This method skips over and discards n bytes of data from this input stream.. |
