ByteArrayInputStream類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()方法用于從此流中跳過給定的字節數(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()方法是一種非靜態方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

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

  skip()方法在跳過字節時不會引發異常。

Syntax:

句法：

public void skip();

Parameter(s):

參數：

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

  long no_of_bytes –表示要跳過的字節數。

Return value:

返回值：

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

該方法的返回類型為long ，它返回要跳過的確切字節數。

Example:

例：

// Java program to demonstrate the example // of long skip(long no_of_bytes) method of // ByteArrayInputStreamimport 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 readingInteger n_byte = byte_s.available();System.out.println("Left avail bytes = " + n_byte);// Read character from the streamchar ch1 = (char) byte_s.read();char ch2 = (char) byte_s.read();char ch3 = (char) byte_s.read();// Display valuesSystem.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

輸出量

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