我的代码看起来像这样

File Fileright = new File("C:\\GamesnewOrder.txt");

PrintWriter pw = new PrintWriter(Fileright);

for(int i =0;i<=Games2.length-1;i++)

{

pw.println(Games2[i]);

}

pw.close();

我确实有throwsIOException的main方法.

错误java.iofilenotfound异常一直出现在我创建printwriter的行.那么打印机没有创建文件？

解决方法:

代码适合我.

import java.io.File;

import java.io.FileNotFoundException;

import java.io.PrintWriter;

public class NewClass {

void n() throws FileNotFoundException {

File Fileright = new File("/home/ubuntu/Documents/f.txt");

PrintWriter pw = new PrintWriter(Fileright);

for (int i = 0; i <= 3; i++) {

pw.println(i);

System.out.println(i);

}

pw.close();

}

public static void main(String[] args) throws FileNotFoundException {

new NewClass().n();

}

}

输出:(在文件中：/home/ubuntu/Documents/f.txt)
