Area of Triangle in Java Example

Here is the Java Example for Area of Triangle

class AreaofTriangle 
 { 
             public  static  void  main  (String  args [ ] ) 
             { 
                         int b,h; 
                         float  a; 
                         b =17; 
                         h=23; 
                         a= (float) 1/2*b*h; 
                         System.out.println("Area  of  Triangle  is  "+a); 
             } 
  
 } 
 

(float) before 1/2 is used for typecasting. If we divide two integers, the result is also as integer. The benefit of using (float) is that it converts 1/2 into 1.0/2.0 and obviously we get the result as 0.5. If we don’t typecast 1/2, then the result of division of two integers is also an integer, hence the result of ½ comes out to be 0, so it is compulsory to typecast an expression which has a / (divide sign).
