以下实例演示了使用 File 类的 dir.list() 方法在指定目录中查找所有文件列表：
Main.java 文件
import java.io.File;
public class Main {
public static void main(String[] argv) throws Exception {
File dir = new File("../java");
String[] children = dir.list();
if (children == null) {
System.out.println("该目录不存在");
}
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：
Car.class FileUtil.class FileUtil.java HelloWorld.class HelloWorld.java HelloWorldDebug.class HelloWorldDebug.java ……
