filetest.java

Java语言程序设计-源代码（第三部分）和课程相对应的提供了一些用于学习理解的代码设计

import java.io.*;

public class FileTest
{
	public static void main( String args[] )
	{
		String fileName = "e:/example.txt";
		File f1 = new File( fileName );
        File f2=new File("e:/FileTest.txt");
		System.out.println("properties of file " + fileName );
		System.out.println("getName() : " + f1.getName() );
		System.out.println("getPath() : " + f1.getPath() );
		System.out.println("getAbsolutePath() : " + f1.getAbsolutePath() );
		System.out.println("getParent() : " + f1.getParent() );
		System.out.println("exists() : " + f1.exists() );
		System.out.println("canRead() : " + f1.canRead() );
		System.out.println("canWrite() : " + f1.canWrite() );
		System.out.println("length() : " + f1.length() );
		System.out.println("isFile() : " + f1.isFile() );
		System.out.println("isDirectory() : " + f1.isDirectory() );
