Question 4: int i = 10.0; Its incorrect as by default decimal value is double and we're attempting to assign to int type which (higher byte size to lower byte size). Which will give Compile Time error as possible lossy conversion/ possible loss of precision. Hence options d is also incorrect.
8 th question i got possiable lossy conversion from double to long,I think double is higher range not depending on type , class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); long a= 10; double b=20; long c=a+b; System.out.println(c); } }
For Question 18: They are reserved words (for the future use). The true false and null − True, false and null represents certain values in Java, they are used as literals. They are not considered as keywords
Q:8---Falae
Q4, option d) is not correct also because 10.0 is double and not int so , response are b) and d)
I am gona share this to my friends who is preparing for the interviews.

float a=10; is correct but float a=10.0 must be incorrect;
