) The _____ method of a radio button returns true if that button is on.

Lostsunrise [7]

Answer:

isSelected()

Explanation:

The isSelected() method of a radio button returns true if that button is on and false otherwise. This method is defined in the class javax.swing.AbstractButton. JRadioButton class inherits from AbstractButton and thus has access to this method. An application code can invoke this method on the radio button instance to determine th ecurrent state and alter the control flow accordingly.

Consider a sequence of 1's and 1's with the property that the sum of any prefix of the sequence is never negative For example th

MrMuchimi

Answer:

Check the explanation

Explanation:

Answer: Solution: Algorithm:

Step 1: Start.

Step 2: Create a stack Step

3: Push an initial stack variable, it will represent that, stack is empty.

Step 4: Get input

If +1 then push "+1"

Else if -1 then pop

Step 5: Repeat until all input finish or Stop if empty stack variable popped. Step 6: Stop.

It is a pushdown automata problem.

It can be also represented as:

X =1+1* —1* 1No(+1)>= No(-1)}

Just five types of pointing device,list

posledela

Answer:

five types of pointing devices

Explanation:

Ponting devices

Pointing means point something and the pointing devices are the input /peripheral devices those are used to point the pointer on the screen. We do move cursor on the screen to open the files or any icon.

There are many types of pointing devices but these are quite common which are given below

Computer mouse
Finger on touch screen.
Joystick.
Leap Motion.
Light pen (pen)

1.Mouse

Mouse is most common type of input device that is used for pointing the data on the screen. We press it with our hands and keep pointing the things.

There are three types of mouse

optical mouse
wireless mouse
trackball mouse.

2. Finger on touch screen

In this type of movement the fingers are input devices those we use to see the movement of pointer on the screen and this is most common in this century.

3.Joystick.

Joystick is another input device to point the cursor but it is mostly used in games. Children can use it smartly so it is inculcated in games usually.

4. Leap Motion

The Leap Motion (LM) controller is a latest 3D sensing device for hand posture interaction with a computer. It is having the capability sense the location of the fingers of the hands, as well as the palm position.

5.Light Pen

this is another pointing device which is mostly used to highlight and select the data on the screen.

Note: All of these above pointing devices are most common used now a days. These devices are having new conventions day by day for the ease of user. This era is basically the era of IT ,so the use of computer must be so easy and conventional for the user so, the innovations and improvement in such devices is made side by side.

Determine the number of bytes necessary to store an uncompressed RGB color image of size 640 × 480 pixels using 8, 10, 12 and 14

dexar [7]

Answer:

For 8 bits / Color Channel: 921, 600 bytes.

For 10 bits / Color Channel: 1,152,000 bytes.

For 12 bits / Color Channel: 1,382,400 bytes.

For 14 bits / Color Channel : 1,612, 800 bytes.

Explanation:

Un uncompressed RGB color image of 640 pixels wide by 480 pixels height (VGA resolution) uses 3 samples of x bits fin order to represent the quantity of each primary color (red, green and blue) in a given pixel of the image.

So, if we use 8 bits/ sample, we can calculate the bytes needed to store a complete image as follows:

640*480*3*8 bits = 7, 372,800 bits. (1)

As, by definition, 1 byte= 8 bits, we have:

Nº of bytes = 7,372,800 / 8 = 921,600 bytes. (2)

In order to get the bytes needed to store the same image, using 10, 12 and 14 bits/ sample, all we need is replacing 8 by 10, 12 and 14 in (1), and then dividing by 8 as in (2).

Proceeding in this way we obtain:

640*480*3*10 = 9,216,000 bits ⇒ 1,152,000 bytes.

640*480*3*12 = 11,059,200 bits ⇒ 1,382,400 bytes.

640*480*3*14= 12,902,400 bits ⇒ 1,612,800 bytes.
