以下示例显示java.io.FileOutputStream.write(byte [] b)方法的用法。
package com.jc2182;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
public class FileOutputStreamDemo {
public static void main(String[] args) throws IOException {
FileOutputStream fos = null;
FileInputStream fis = null;
byte[] b = {65,66,67,68,69};
int i = 0;
char c;
try {
// create new file output stream
fos = new FileOutputStream("C://test.txt");
// writes bytes to the output stream
fos.write(b);
// flushes the content to the underlying stream
fos.flush();
// create new file input stream
fis = new FileInputStream("C://test.txt");
// read till the end of the file
while((i = fis.read())!=-1) {
// convert integer to character
c = (char)i;
// prints
System.out.print(c);
}
} catch(Exception ex) {
// if an error occurs
ex.printStackTrace();
} finally {
// closes and releases system resources from stream
if(fos!=null)
fos.close();
if(fis!=null)
fis.close();
}
}
}
