FilterInputStream類skip()方法 (FilterInputStream Class skip() method)

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

  skip()方法在java.io包中可用。

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

  skip()方法用于從此FilterInputStream跳過給定數(shù)目的數(shù)據(jù)字節(jié)。

• 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(tài)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 may throw an exception at the time of skipping bytes of data.

  skip()方法在跳過數(shù)據(jù)字節(jié)時可能會引發(fā)異常。

  IOException: This exception may throw when the given parameter is invalid.

  IOException ：如果給定參數(shù)無效，則可能引發(fā)此異常。

Syntax:

句法：

public long skip(long number);

Parameter(s):

參數(shù)：

• long number – represents the number of bytes to be skipped.

  long number –表示要跳過的字節(jié)數(shù)。

Return value:

返回值：

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

該方法的返回類型為long ，它返回跳過的確切字節(jié)數(shù)。

Example:

例：

// Java program to demonstrate the example // of long skip(long number) method // of FilterInputStreamimport java.io.*;public class SkipOfFIS {public static void main(String[] args) throws Exception {FileInputStream fis_stm = null;FilterInputStream fil_stm = null;int count = 0;try {// Instantiates FileInputStream and // FilterInputStreamfis_stm = new FileInputStream("D:\\includehelp.txt");fil_stm = new BufferedInputStream(fis_stm);// Loop to read until available// bytes leftwhile ((count = fil_stm.read()) != -1) {// Display corresponding char valuechar ch = (char) count;// Display value of chSystem.out.println("ch: " + ch);// By using skip() method is// to skip 2 bytes of char value// from fil_stm long skip = fil_stm.skip(2);System.out.println("fil_stm.skip(2): " + skip);}} catch (Exception ex) {System.out.println(ex.toString());} finally {// with the help of this block is to// free all necessary resources linked// with the streamif (fis_stm != null) {fis_stm.close();if (fil_stm != null) {fil_stm.close();}}}} }

Output
