以下实例演示了在 C 盘中查找以字母 'b' 开头的所有文件：
Main.java 文件
import java.io.*;
class Main {
public static void main(String[] args) {
File dir = new File("C:");
FilenameFilter filter = new FilenameFilter() {
public boolean accept
(File dir, String name) {
return name.startsWith("b");
}
};
String[] children = dir.list(filter);
if (children == null) {
System.out.println("目录不存在或它不是一个目录");
}
else {
for (int i=0; i < children.length; i++) {
String filename = children[i];
System.out.println(filename);
}
}
}
}
以上代码运行输出结果为：
build build.xml
