StringBuffer的妙用

String proteinB = proB.toString();
while(proteinB.length() != 0)
{
//# T1 4 7 interferon regulatory factor 4
int loc = proteinB.indexOf("\r\n");
String proSent = proteinB.substring(0, loc);
String[] proInfo = proSent.split(" ");
for(int prosId = 0; prosId < arguIdList.size(); prosId++)
{
if(arguIdList.get(prosId).equals(proInfo[1]))
{
bw.write(proSent);
bw.newLine();
bw.flush();
}
}
proteinB = proteinB.substring(loc+2);
}
