以下示例显示java.io.ByteArrayOutputStream.toString(String charsetName)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 = "";
byte[] bs = {65, 66, 67, 68, 69};
ByteArrayOutputStream baos = null;
try {
// create new ByteArrayOutputStream
baos = new ByteArrayOutputStream();
// write byte array to the output stream
baos.write(bs);
// converts buffers content using Cp1047 character set
str = baos.toString("Cp1047");
System.out.println(str);
// converts buffers contents using UTF-8 character set
str = baos.toString("UTF-8");
System.out.println(str);
} catch(Exception e) {
// if I/O error occurs
e.printStackTrace();
} finally {
if(baos!=null)
baos.close();
}
}
}
