【JAVA应用】输入输出流工具类

package com.example.uril;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;

public class StreamTool {
/*
* 读取流中的数据
* */
public static byte[] read(InputStream inStream) throws Exception {
ByteArrayOutputStream outStream=new ByteArrayOutputStream();
byte[] buffer=new byte[1024];
int len=0;
while((len=inStream.read(buffer))!=-1){
outStream.write(buffer,0,len);
}
inStream.close();
return outStream.toByteArray();
}
