文件复制的疑惑

   下面一个精简版的Task类：

import java.io.File;
import java.util.List;
import java.util.concurrent.CopyOnWriteArrayList;

import org.apache.commons.io.FileUtils;
import org.gradle.api.tasks.TaskAction;

public class MyTask {
	private List<Action> actions = new CopyOnWriteArrayList<>();
	
	public void copy(final String source, final String dest) throws Exception {
		this.actions.add(new Action() {
			@Override
			public void execute() throws Exception {
				FileUtils.copyFile(new File(source), new File(dest));
			}
		});
	}
	
	public void copyDependencies() {
		this.actions.add(new Action() {
			@Override
			public void execute() throws Exception {
				File dir = new File("H:\\sourceDir");//测试代码源目录
				for(File file : dir.listFiles()) {
					copy(file.getAbsolutePath(), "H:\\destDir\\"+file.getName());
				}
			}
		});
	}
	
	@TaskAction
	public void execute() throws Exception {
		for(Action action : this.actions) {
			action.execute();
		}
	}
	
	public static interface Action {
		void execute() throws Exception;
	}

}

import java.io.File;
import java.util.List;
import java.util.ArrayList;

import org.apache.commons.io.FileUtils;
import org.gradle.api.tasks.TaskAction;

public class MyTask {
	private List<Action> actions = new ArrayList<>();
	
	public void copy(final String source, final String dest) throws Exception {
		this.actions.add(new Action() {
			@Override
			public void execute() throws Exception {
				FileUtils.copyFile(new File(source), new File(dest));
			}
		});
	}
	
	public void copyDependencies() {
		this.actions.add(new Action() {
			@Override
			public void execute() throws Exception {
				File dir = new File("H:\\sourceDir");
				for(File file : dir.listFiles()) {
					//不再调用copy方法，而是直接进行文件复制，这样就避免了仅向actions列表中添加元素
					//列表类型也可以使用ArrayList了
					FileUtils.copyFile(file, new File("H:\\destDir\\"+file.getName()));
				}
			}
		});
	}
	
	@TaskAction
	public void execute() throws Exception {
		for(Action action : this.actions) {
			action.execute();
		}
	}
	
	public static interface Action {
		void execute() throws Exception;
	}

}
