以下示例显示java.io.BufferedWriter.write(int c)方法的用法。
package com.jc2182;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.StringWriter;
public class BufferedWriterDemo {
public static void main(String[] args) throws IOException {
StringWriter sw = null;
BufferedWriter bw = null;
try{
// create string writer
sw = new StringWriter();
//create buffered writer
bw = new BufferedWriter(sw);
// integer range represents alphabets in uppercase
for(int i = 65; i<=90; i++)
{
bw.write(i);
}
// forces out the characters to string writer
bw.flush();
// string buffer is created
StringBuffer sb = sw.getBuffer();
// prints the string
System.out.println(sb);
}catch(IOException e){
// if I/O error occurs
e.printStackTrace();
}finally{
// releases any system resources associated with the stream
if(sw!=null)
sw.close();
if(bw!=null)
bw.close();
}
}
}
让我们编译并运行以上程序,这将产生以下结果:
