以下示例显示java.io.FilterInputStream.skip(long n)方法的用法。
package com.jc2182;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FilterInputStream;
import java.io.IOException;
import java.io.InputStream;
public class FilterInputStreamDemo {
public static void main(String[] args) throws Exception {
InputStream is = null;
FilterInputStream fis = null;
int i = 0;
char c;
try {
// create input streams
is = new FileInputStream("C://test.txt");
fis = new BufferedInputStream(is);
while((i = fis.read())!=-1) {
// converts integer to character
c = (char)i;
// skips 3 bytes
fis.skip(3);
// print
System.out.println("Character read: "+c);
}
} catch(IOException e) {
// if any I/O error occurs
e.printStackTrace();
} finally {
// releases any system resources associated with the stream
if(is!=null)
is.close();
if(fis!=null)
fis.close();
}
}
}
假设我们有一个文本文件c:/test.txt ,其内容如下。该文件将用作示例程序的输入-
让我们编译并运行以上程序,这将产生以下结果-
Character read: A
Character read: E
