Java to realize heart-shaped pattern | Peach Heart

There is something wrong if you are thedouble type minus an int type. Because when you are refer to a double type.

Eg. Double 1.0;

Some IDE may get the value 1.00000000000

and others may get 0.999999999999999

But They represent the same number.

The same problem here.

So your must find the precise position.

 

For that we use the function (x^2+y^2-1) ^3-x^2*y^3 = 0;

single Peach Heart:

       public static void Main (String argv[]) {for
              (float y = (float) 1.5;y>-1.5;y-=0.1)
              {for
                     (float x= (float)-1 .5;x<1.5;x+= 0.05)
                     {
                           float a = x*x+y*y-1;
                           if ((a*a*a-x*x*y*y*y) <=0.0)
                           {
                                  
                                  
                                  System.out.print ("*");
                           
                           }
                           else
                                  System.out.print ("");
                     }
                     System.out.print ("\ n");
              }
