filewriter.java

由于想一次上传成功 所以将二个教程打包成了一个 这些例子几乎包含了所有java的框架集合

import java.io.*;

class filewriter 
{
    public static void main(String args[]) throws Exception 
    {
        char data[] = {'T','h','i','s',' ','i','s',' ','a',' ','s','t','r','i','n','g',' ','o','f',
            ' ','t','e','x','t','.'};

        FileWriter filewriter1 = new FileWriter("file1.txt");
        for (int loop_index = 0; loop_index < data.length; loop_index++) {
            filewriter1.write(data[loop_index]);
        }

        FileWriter filewriter2 = new FileWriter("file2.txt");
        filewriter2.write(data);

        FileWriter filewriter3 = new FileWriter("file3.txt");
        filewriter3.write(data, 5, 10);

        filewriter1.close();
        filewriter2.close();
        filewriter3.close();
    }
}
