介绍

Java.io.InputStream类是表示字节输入流的所有类的超类。需要定义InputStream的子类的应用程序必须始终提供一种返回下一个输入字节的方法。

类声明

以下是Java.io.InputStream类的声明-

public abstract class InputStream
   extends Object
      implements Closeable

类的构造函数

Sr.No. Constructor & Description

Single Constructor

类方法

Sr.No. Method & Description
1 int available()

This method returns 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.
