writetofile.java

一本书中的原代码,有用多例子,很好用

package Test;

import java.io.*;
public class WritetoFile {
    private String path;
    //文件路径
    private String something;
    //写入的数据
    
    /** Creates a new instance of WriteFile */
    public WritetoFile() {
        //初始化
        path = null;
        something="缺省文字";
    }
    
    public void setPath(String apath) {
        //设置文件路径
        path = apath;
    }
    
    public String getPath() {
        //得到文件路径
        return path;
    }
    
    public void setSomething(String asomething) {
        //得到字符串
        something = asomething;
    }
    
    public String getSomething() {
        //设置字符串
        return something;
    }
    
    public String writeSomething() {
        //写入字符串到文件中，如果成功则返回显示“写入文件成功！”
        try {
            File f = new File(path);
            PrintWriter out = new PrintWriter(new FileWriter(f));
            out.print(this.getSomething()+"\n");
            
            out.close();
            return "写入文件成功！";
        } catch (IOException e) {
            return e.toString();
        }
        
    }
    
}
