# Java program to convert integer value into binary

Let’s learn java program to convert integer value into binary.

## Java program to convert integer value into binary

To convert an integer value to binary first user enters an integer number as input using nextInt() method of Scanner class.

This number is stored in integer variable num. Then using while loop we check variable num is greater than 0.

If variable num is greater than zero then inside while loop using modulus and division operator given input is converted into binary. Here’s how to convert integer value to binary in java.

```import java.util.*;
import java.util.Scanner;
public class IntegerToBinary
{
public static void main(String[] args)
{
int num;
String str = "";
Scanner sc = new Scanner(System.in);
System.out.println("Please enter the a number : ");
num = sc.nextInt();
// convert int to binary java
while(num > 0)
{
int y = num % 2;
str = y + str;
num = num / 2;
}
System.out.println("The binary conversion is : " + str);
sc.close();
}
}
```

Output:

Please enter the a number : 12
The binary conversion is : 1100
