What are the two types of primitive data type conversion?
Type Casting/type conversion Converting one primitive datatype into another is known as type casting (type conversion) in Java. You can cast the primitive datatypes in two ways namely, Widening and, Narrowing.
What is datatype conversion?
In computer science, type conversion, type casting, type coercion, and type juggling are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa.
Is short a primitive data type?
A primitive type is predefined by the language and is named by a reserved keyword. short: The short data type is a 16-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive).
Does Java allow narrowing conversions?
Narrowing conversion is needed when you convert from a larger size type to a smaller size. This is for incompatible data types, wherein automatic conversions cannot be done.
What does a primitive mean in computer graphics?
Points and lines, polygons, filing of polygons, text primitive, windowing and clipping, view port A primitive is a low level object or operation from which higher-level, more complex objects and operations can be constructed.
How to draw a line in graphic primitive?
The line primitive is drawn by sending out the “Draw line primitive” opcode (0xD9), followed by the x-coordinate of point 1, the y-coordinate of point 1, the x-coordinate of point 2, the y-coordinate of point 2, the line pattern and finally the line weight. The x and y coordinates are 16-bit numbers.
How to define persistence in Computer Graphics Unit I?
Persistence is defined as the time it takes the emitted light from the screen to decay to one tenth of its original intensity. 2. Define resolution. The maximum number of points that can be displayed without overlap on a CRT is referred to as the resolution.
How does a pixel primitive draw a pixel?
The pixel primitive draws a single pixel at a given point (x and y coordinates), plus a line weight and line pattern. The pixel primitive is drawn by sending out the “Draw rectangle primitive” opcode (0xDC), followed by the x-coordinate of the point, the y-coordinate of the point, the fill pattern and finally the line weight.
