我在一个文件夹中有几个大的 DB 文件,我在 JAVA 中处理了一段时间,如何使用 JProgressbar 显示剩余时间的百分比?
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;
}
多谢 ...
