ByteArrayInputStream类skip()方法 (ByteArrayInputStream Class skip() method)

• skip() method is available in java.util package.

  skip()方法在java.util包中可用。

• skip() method is used to skip the given number of bytes (no_of_bytes) from this stream.

  skip()方法用于从此流中跳过给定的字节数(no_of_bytes)。

• skip() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.

  skip()方法是一种非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。

• skip() method does not throw an exception at the time of skipping bytes.

  skip()方法在跳过字节时不会引发异常。

Syntax:

句法：

    public void skip();

Parameter(s):

参数：

• long no_of_bytes – represents the number of bytes to skip.

  long no_of_bytes –表示要跳过的字节数。

Return value:

返回值：

The return type of the method is long, it returns the exact number of bytes to be skipped.

该方法的返回类型为long ，它返回要跳过的确切字节数。

Example:

例：

// Java program to demonstrate the example
// of long skip(long no_of_bytes) method of
// ByteArrayInputStream
import java.io.*;
public class SkipBAIS {public static void main(String[] args) throws Exception {byte[] by = {97,
98,
98,
99,
100
};
// Instantiates ByteArrayInputStream
ByteArrayInputStream byte_s = new ByteArrayInputStream(by);
// By using available() method is to
// return the no. of bytes to be left
// for reading
Integer n_byte = byte_s.available();
System.out.println("Left avail bytes = " + n_byte);
// Read character from the stream
char ch1 = (char) byte_s.read();
char ch2 = (char) byte_s.read();
char ch3 = (char) byte_s.read();
// Display values
System.out.println("ch1: " + ch1);
System.out.println("ch2 : " + ch2);
System.out.println("ch3: " + ch3);
// It skip 1 bytes of data
// from the stream
byte_s.skip(1);
char ch = (char) byte_s.read();
System.out.println("ch: " + ch);
byte_s.close();
}
}

Output

输出量

Left avail bytes = 5
ch1: a
ch2 : b
ch3: b
ch: d
