我在一个文件夹中有几个大的数据库文件,我用JAVA处理它们一段时间后,如何使用JProgressbar显示剩余时间百分比?用jprogressbar显示剩余时间?
public int countTrueAmr(String text, String under,String value, String search) {
int sLen = under.length();
int count = 0;
int index = text.indexOf(under + value, 0);
int nextIndex = text.indexOf(under, index + sLen);
while (index > 0 && nextIndex > 0) {
count += countString(text.substring(index, nextIndex), search);
index = text.indexOf(under + value, index + sLen);
nextIndex = text.indexOf(under, index + sLen);
if (nextIndex < 0)
nextIndex = text.length();
}
return count;
}
非常感谢......
