Write a program, NumberStatistics.java, that reads an unspecified number of integers. The program ends with the input 0. The pro

Lerok [7]

Answer:

Following are the program, which can be below:

import java.util.*; //defining header file

public class NumberStatistics //defining class NumberStatistics

{

public static void main(String[] arc) //defining main method

{

int total_number=0,max_val=0,min_val=0,neg_val=0,pos_val=0,neg_count=0,pos_count=0,x; //defining variables

Scanner ox= new Scanner(System.in); //creating Scanner class Object

System.out.println("Enter positive and negative value with sign and when complete inter 0:"); //print message

x= ox.nextInt(); //input value from user

while(x!=0) //defining loop to check input value is 0

{

total_number++; // increment value

if(total_number == 1) //defining conditional statement to check minimum and maximum value

{

max_val = x; //assign value in max

min_val = x;//assign value in min

}

else //defining else block

{

if(max_val < x) //check maximum value

{

max_val = x; //assign maximum value

}

if(min_val > x) //check minimum value

{

min_val = x; //assign minimum value

}

if(x > 0) //input values

{

pos_count++; //count positive value

pos_val+=x; // add positive values

}

else

{

neg_count++;//count negative value

neg_val+=x; // add negative values

}

x = ox.nextInt(); //input values

}

// defining conditionl statement

if(total_number != 0) // defining if block to print all value

{

System.out.println("positive value average= "+(pos_val/(double)pos_count));

System.out.println("negative values Average= "+(neg_val/(double)neg_count));

System.out.println("all values average= "+(pos_val+neg_val)/(double)total_number);

System.out.println("maximum value = "+max_val+"\n"+" minimum value = "+min_val);

}

else

{

System.out.println("no positive values found");

System.out.println("no negative values found");

}

Output:

Enter positive and negative value with sign and when complete inter 0:

12

8

04

22

-22

-5

9

0

positive value average= 11.0

negative values Average= -13.5

all values average= 4.0

maximum value = 22

minimum value = -22

Explanation:

The Description of the above java program can be described as follows:

In the above code first we import the package for user input, then defines the variable "total_number,max_val,min_val,neg_val,pos_val,neg_count, pos_count,x" to store the value prints its value.
In the next step, a scanner class object is created for user input and defines a while loop, that checks input value isn't equal to 0, inside the loop a conditional statement defines that cont and calculates all positive, negative, and all values addition.
At the another conditional statement is defines, that prints all value average, and also prints maximum, minimum value.

write a loop that reads positive integers from stands input and that terinated when it reads an interger that is not positive af

gtnhenbr [62]

Loop takes only positive numbers and terminates once it encounters a negative numbers.

Answer and Explanation:

Using javascript:

Var positiveInt= window.prompt("insert positive integer");

While(positiveInt>=0){

Alert("a positive integer");

Var positiveInt= window.prompt("insert positive integer");

}

Or we use the do...while loop

Var positiveInt= window.prompt("insert positive integer");

do{

Var positiveInt= window.prompt("insert positive integer");

}

While (positiveInt>=0);

The above program in javascript checks to see if the input number is negative or positive using the while loop condition and keeps executing with each input until it gets a negative input

In the RGB color model, what do numbers 0-255 represent

Ludmilka [50]

In the RGB (Red, Green, Blue) color model, the numbers 0-255 represent the intensities of each color beam .Each number represents an intensity value is on a scale of 0 to 255, It can be also written in hexadecimal form, from 00 to FF.

RGB values are encoded as 8-bit integers, which range from 0 to 255.
