随机密码javabean源代码
刚刚写了一个可以设定位数的生成随机密码的bean希望对新手朋友有点用，呵呵

package com.cn;public class PwdBean {//密码位数private int pwdnum;//密码private long passwd;//空构造函数public PwdBean(){}//生成密码public void createPasswd(){double d=Math.random();int n=1;for(int i=0;i<pwdnum;i++){n=n*10;}passwd=(long)(d*n);}//得到密码public long getPasswd(){return this.passwd;}         //设定密码长度public void setPwdnum(int pwdnum) {if(pwdnum<6){this.pwdnum=6;}else if(pwdnum>8){this.pwdnum=8;}else{this.pwdnum=pwdnum;}}public int getPwdnum() {return pwdnum;}}
