Java Program to convert from decimal to binary
To convert decimal to binary, Java has a method Integer.toBinaryString(). The method returns a string representation of the integer argument as an unsigned integer in base 2.
Let us first declare and initialize an integer variable.
int dec = 25;
Convert it to binary.
String bin = Integer.toBinaryString(dec);
Now display the “bin” string, which consists of the Binary value. Here is the complete example.
Example
public class Demo { public static void main( String args[] ) { int dec = 25; // converting to binary and representing it in a string String bin = Integer.toBinaryString(dec); System.out.println(bin); } }
Output
11001
