Java program converts decimal to binary

To convert decimal to binary, Java has a method 'Integer.toBinaryString()'. This method returns the string representation of an integer parameter as a base2Unsigned integer with base 10.

Let's first declare and initialize an integer variable.

int dec = 25;

Convert it to binary.

String bin = Integer.toBinaryString(dec);

Now display the 'bin' string composed of binary values. This is a complete example.

Example

public class Demo {
   public static void main(String args[]) {
      int dec = 25;
      //Convert to binary and represent it as a string
      String bin = Integer.toBinaryString(dec);
      System.out.println(bin);
   }
}
