Java Basic(81)- Reading from Files

創建新的class - readfile
import java.io.*;

import java.util.*;

public class readfile {

private Scanner x; →從文件或鍵盤讀取

public void openFile(){

try{

x= new Scanner(new File("chinese.txt"));

}

catch(Exception e){

System.out.println("could not find file");

}

}

public void readFile(){

while(x.hasNext()){ →循環每個項目（字符串）

String a = x.next();

String b = x.next();

String c = x.next();

System.out.printf("%s %s %s\n",a,b,c);

}

}

public void closeFile(){ →關閉文件

x.close();

}

}

class apples{

public static void main(String[] args){

readfile r = new readfile();

r.openFile();

r.readFile();

r.closeFile();

}

}
