# Java: Input 5 numbers from keyboard and find their sum and average

## Java Conditional Statement: Exercise-12 with Solution

Write a program in Java to input 5 numbers from the keyboard and find their sum and average.

Test Data
Input the 5 numbers: 1 2 3 4 5

Pictorial Presentation: Sample Solution:

Java Code:

``````import java.util.Scanner;
public class Exercise12 {

public static void main(String[] args)

{
int i,n=0,s=0;
double avg;
{

System.out.println("Input the 5 numbers : ");

}
for (i=0;i<5;i++)
{
Scanner in = new Scanner(System.in);
n = in.nextInt();

s +=n;
}
avg=s/5;
System.out.println("The sum of 5 no is : " +s+"\nThe Average is : " +avg);

}
}
```
```

Sample Output:

```Input the 5 numbers :
1
2
3
4
5
The sum of 5 no is : 15
The Average is : 3.0
```

## Java: Tips of the Day

IsPowerOfTwo

Checks if a value is positive power of two.

To understand how it works let's assume we made a call IsPowerOfTwo(4).

As value is greater than 0, so right side of the && operator will be evaluated.

The result of (~value + 1) is equal to value itself. ~100 + 001 => 011 + 001 => 100. This is equal to value.

The result of (value & value) is value. 100 & 100 => 100.

This will value the expression to true as value is equal to value.

```public static boolean isPowerOfTwo(final int value) {
return value > 0 && ((value & (~value + 1)) == value);
}
```
