這一段是什么意思？為什么字節(jié)數(shù)組里面要放8*1024
FileInputStream in=new FileInputStream(srcFile);
?? ??? ???? FileOutputStream out=new FileOutputStream(desFile);
??????????? byte[] suo=new byte[8*1024];
??????????? int b;
??????????? while((b=in.read(suo,0,suo.length))!=-1){
?????????? ??? ?out.write(suo, 0, b);
?????????? ??? ?out.flush();
??????????? }

1024字節(jié)就是1KB大小，8*1024個字節(jié)就是8KB，湊個整方便些
