以下示例显示java.io.InputStream.skip(long n)方法的用法。
package com.jc2182;
import java.io.FileInputStream;
import java.io.InputStream;
public class InputStreamDemo {
public static void main(String[] args) throws Exception {
InputStream is = null;
int i;
char c;
try {
// new input stream created
is = new FileInputStream("C://test.txt");
while((i = is.read())!=-1) {
// converts int to char
c = (char)i;
// prints character
System.out.println("Character Read: "+c);
// skip one byte
is.skip(1);
}
} catch(Exception e) {
// if any I/O error occurs
e.printStackTrace();
} finally {
// releases system resources associated with this stream
if(is!=null)
is.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: C
Character Read: E
