# Java program to check nth bit of 16-bit number is set or not

Given/input a short integer (i.e., 16-bit number), we have to check its nth bit is set or not.
Submitted by Nidhi, on March 10, 2022

Problem Solution:

In this program, we will read a 16-bit integer number from the user. Then we will check nth bit of the 16-bit number is set or not.

Program/Source Code:

The source code to check nth bit of the 16-bit number is set or not is given below. The given program is compiled and executed successfully.

```// Java program to check nth bit of
// 16-bit number is set or not

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner SC = new Scanner(System.in);

short n = 0;
short k = 0;

System.out.printf("Enter a 16 bit number: ");
k = SC.nextShort();

System.out.printf("Enter the bit number: ");
n = SC.nextShort();

if (n < 0 || n > 16) {
System.out.printf("Enter between 0-15\n");
return;
}

k = (short)(k >> n);

if ((k & 1) == 1)
System.out.printf("BIT number %d is set\n", n);
else
System.out.printf("BIT number %d is not set\n", n);
}
}
```

Output:

```Enter a 16 bit number: 9
Enter the bit number: 3
BIT number 3 is set
```

Explanation:

In the above program, we imported the "java.util.Scanner" package to read the variable's value from the user. And, created a public class Main. It contains a static method main().

The main() method is an entry point for the program. Here, we read a 16-bit integer and bit number from the user using Scanner class and checked bit number of the given number is HIGH or not and printed the appropriate message.
