Java 最简单的文件输入输出(给自己看)

文件的输入输出,之前看过多次,但每次都忘,这次总结一下,以备之后翻看;

代码:

import java.io.IOException;
import java.io.PrintWriter;
import java.nio.file.Paths;
import java.util.Scanner;

public class FirstForTest {
	public static void main(String[] args) throws IOException {
		Scanner in = new Scanner(Paths.get("E:\\Eclipse\\workspace\\ForStudy\\src\\Torres.txt"));
		while(in.hasNext()) {
			System.out.println(in.nextLine());	//read the file's content and print it on console;
		}
		in.close();
		
		PrintWriter out = new PrintWriter("E:\\Eclipse\\workspace\\ForStudy\\src\\Lan.txt");
		out.println("Hi, Lan; \n I touch you in Java-Eclipse!");	//write the content on specific file.
		out.close();
	}
}
注意:如果文件名中包含"\", 就要记住在每个反斜杠之前再加一个额外的反斜杠;
