以下示例显示java.io.ByteArrayOutputStream.size()方法的用法。
package com.jc2182;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
public class ByteArrayOutputStreamDemo {
public static void main(String[] args) throws IOException {
String str = "";
int size = 0;
byte[] bs = {65, 66, 67, 68, 69};
ByteArrayOutputStream baos = null;
try {
// create new ByteArrayOutputStream
baos = new ByteArrayOutputStream();
// for each byte in the buffer
for (byte b : bs) {
// write byte in to output stream
baos.write(b);
// convert output stream to string
str = baos.toString();
size = baos.size();
// print
System.out.print(size+":");
System.out.println(str);
}
} catch(Exception e) {
// if I/O error occurs
e.printStackTrace();
} finally {
if(baos!=null)
baos.close();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
1:A
2:AB
3:ABC
4:ABCD
5:ABCDE
