做一个简单的javabean（判断输入三边是否能构成三角），运行出错：Cannot find any information on property '*' ，还请哪位高人讲解，不盛感激
Java代码如下：package pandu;
public class panduan
{
int biana = 0;
int bianb = 0;
int bianc = 0;
String outp = "";
public void setbiana (int biana)
{
this.biana = biana;
}
public int getbiana ()
{
return biana;
}
{
this.biana = biana;
}
public String getoutp ()
{
return outp;
}
public void setoutp (String outp)
{
this.outp = outp;
}
public int getbianb ()
{
return bianb;
}
public void setbianc (int bianc)
{
this.bianc = bianc;
}
public int getbianc ()
{
return bianc;
}
public void panduanabc()
{
if ((biana + bianb > bianc) && (biana + bianc > bianb) && (bianb + bianc > biana))
{
this.setoutp("能") ;
}
else
{
this.setoutp("不能") ;
}
}
/*
public static void main(String args[])
{
panduan a = new panduan();
a.panduanabc();
System.out.println(a.outp);
}
*/
}

--------------------编程问答-------------------- bean的格式应该是getXxxx吧，比如说，你的getbiana（），就应该是getBiana（），要不是找不到bean的 --------------------编程问答-------------------- 挺好的呵呵呵谢谢了
补充：Java , Web 开发
