向文件写入内容

static String path = File.separator + "E:" + File.separator + "cxd" +
File.separator + "work" + File.separator + "a.txt";

/**
* @param args
*/
public static void main(String[] args) {
//创建文件对象
File file = new File(path);

PrintWriter p = null;
try {
//p=new PrintWriter(file);
p = new PrintWriter(new FileWriter(file,true));//利用FileWriter构建PrintWriter对象，实现追加
//
p.println("1334");

//刷新流
p.flush();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
p.close();
