复制代码 代码如下:
string filename = "d:/date.java.bak";
// string filename = "d:/test.qqq";
string line;
int i = 0, j = 0, f = 0, k = 0;
try {
bufferedreader in = new bufferedreader(new filereader(filename));
line = in.readline();
while (line != null) {
// system.out.println(line);
char c[] = line.tochararray();
for (int i1 = 0; i1 < c.length; i1++) {
// 如果是字母
if (character.isletter(c[i1]))
i++;
// 如果是数字
else if (character.isdigit(c[i1]))
j++;
// 是空格
else if (character.iswhitespace(c[i1]))
f++;
}
line = in.readline();
k++;
}
in.close();
system.out
.println("字母:" + i + ",数字:" + j + ",空格:" + f + ",行数:" + k);
} catch (ioexception e) {
e.printstacktrace();
}
