Answer:
Option (D) using the private access specifier on the class fields
Explanation:
- The private access modifier can be used to hide the data.
- Methods and data variables ( fields ) can be declared with the private access modifier.
- Data hiding is a OOPS Concept which can be achieved with the private keyword (private access modifier).
- The access modifiers are of types Public, Private, Protected and Default ( no access modifier - no need to explicitly specify the default keyword).
- Data hiding means to hide the data, the data is contained in the class variables.So, option (d) using private access modifier on the class fields is correct option.
- Option (A) is wrong as the using the public access modifier doesn't hide anything. It is public and is visible to the public.
- Option (B) is wrong as using the private access modifier on the methods means it is hiding the implementation of the methods not the data.
- Option (C) is wrong as using private access modifiers on class definition means making the classes not visible to other classes it doesn't mean data hiding as the data is contained in the class variables.
Answer:
B. It uses "Light-years" to talk about time, but a light-year is a unit of distance.
Explanation:
Light-Year is a term used in astronomy to describe the distance that light travels in a year. Informally, astronomers use the light year to describe distances between planets, stars, moons and other astronomical bodies.
Light-years are sometimes mistakenly thought of as units of time — because of the year — but they're actually units of distance, equal to about six trillion miles. In 1851, the light year was first used for defining distances by a German astronomer who compared it to a "hiking hour," or the distance a person can hike in one hour. The term can also figuratively mean "a long way:"
Answer:
If left being the shortest file size and right being the biggest file size...
It is JPEG, PNG, TIFF.
Explanation:
TIFF is used primarily for editing photos or for uncompressed high quality images for things like 4K textures. The file size will be bigger since generally it is uncompressed.
PNG reserves the maximum quality of the image and can not be compressed. (It can be compressed but the results are very minimal).
JPEG allows for the user to decide the compression and quality of the image. JPEG also doesn't hold transparency data, thus making JPEG generally use less space than PNG and definitely more than TIFF.
