3. D:
   # javac Test33.java
   Test33.java:10: error: possible loss of precision
   float flt = y1;
   ^
   required: float
   found: double
   1 error
   ———————–
   to compile without error its needed casting: float flt = (float) y1

4. Answer D:

   By default, any decimal point number is of type “double”. Therefore, whenever we assign a decimal number to a float variable, we either have to use “f” postfix, or to cast that number to (float).

5. public class Test {
   public static void main(String[] args) {
   float flt = 100F;
   float flt1 = (float) 1_11.00;
   float flt2 = 100;
   double y1 = 203.00;
   float flt3 = y1; //Type mismatch: cannot convert from double to float
   int y2 = 100;
   float flt4 = y2;
   }
   }
