如何在JSP中定义一个返回boolean型的方法，该方法如何调用！！
我是这样做的：
 public boolean f(){        
        
      for(x=0;x<3;x++)
             for(y=0;y<67;y++)                  
                   for(z=0;z<3;z++)
                          for(q=0;q<67;q++)
                                    {if(C[x][y]==D[z][q]&&C[x][y]!=""&&C[x][y]!=null&&D[z][q]!=""&&D[z][q]!=null)
                                      return true;
                                      //out.println(C[x][0]);
                                      //out.println(D[z][0]);
                                      break;
                                      
                                      }
                                      else return false;
                    }
                    
if(f())
{
   out.println(C[x][0]);
   out.println(D[z][0]);
}
else out.println("无相交点");

编辑时老是说方法定义有误 ！希望大家帮解决一下！！
