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.
memory addresses which is roughly equivalent to 4 GB of memory.
memory addresses which equates to a huge amount of memory, 16 exabytes to be precise.
