FIleInputStream.read()方法小解

原来文件读取的是二进制字节内容，对应的是字母的acII值，如下用例可以让你看到取到的到底时什！！
public static void main(String args[]) throws IOException{
File file=new File("E:/j2ee-project/work-space-01/edu/src/trm/com/hnyyzw/trm/model/TrmFile.java");
if(file.exists()){
FileInputStream inputStream = new FileInputStream(file);
int size=0;
System.out.println("inputstream available:"+(double)inputStream.available()/1024);
for(double i=0;(size=inputStream.read())!=-1;i++){
System.out.println((char)size);
System.out.println("xxx:"+size);
}
}
}
