Explain how to create colors using RGB values.
What will be an ideal response?
The syntax for assigning a color unit with an RGB value is RGB(red, green, blue). Each color value is a number ranging from 0 to 255, which indicates its intensity. A value of 0 indicates that the color should include the minimum intensity of a primary color, and a value of 255 indicates that the color should include the maximum intensity. By combining different intensities of the red, green, and blue primary colors, you can come up with millions of different hues. You create primary colors of red, green, or blue by using a full intensity value of 255 for one of the primary colors, and values of 0 for the two other primary colors. For example, you use the following RGB value to assign the color red to the color property: color: RGB(255, 0, 0).

Which of the following statements is false?
a. If an operation requires the executing thread to hold a lock while the operation is performed, a thread must relase the lock before proceeding with the operation. Other threads attempting to perform an operation that requires the same lock will be blocked until the first thread releases the lock, at which point the blocked threads may attempt to acquire the lock and proceed with the operation. b. To specify that a thread must hold a monitor lock to execute a block of code, the code should be placed in a synchronized statement. c. Code in a synchronized statement is said to be guarded by the monitor lock; a thread must acquire the lock to execute the guarded statements. d. The monitor allows only one thread at a time to execute statements within synchronized statements that lock on the same object, as only one thread at a time can hold the monitor lock. The synchronized statements are declared using the synchronized keyword.
