How do you write a Java program to convert a decimal number to an octal number?

Answer 1

public class Dataconversion {

public static void main(String[] args) {

System.out.println("Data types conversion example!");

int in = 44;

System.out.println("Integer: " + in);

//integer to binary

String by = Integer.toBinaryString(in);

System.out.println("Byte: " + by);

//integer to hexadecimal

String hex = Integer.toHexString(in);

System.out.println("Hexa decimal: " + hex);

//integer to octal

String oct = Integer.toOctalString(in);

System.out.println("Octal: " + oct);

}

}

Answer 2

Here is a simple way to display a decimal integer as an octal number:

Integer i = 10;

System.out.println(Integer.toOctalString(i));
