# Recursion – java program to convert decimal to octal

Hey guys!! Welcome to flower brackets blog. Let’s learn recursion – java program to convert decimal to octal.

#### Recursion – java program to convert decimal to octal

Here we are going to see java program to convert decimal to octal using recursion or recursive method,

`import java.util.Scanner;`
`public class DecimalToOctalExample{   static int octal[] = new int, x = 1;   int[] convertToOctal(int oct)   {      if(oct != 0)      {         octal[x++] = oct % 8;         oct = oct / 8;         convertToOctal(oct);      }      return octal;   }   public static void main(String[] args)   {      DecimalToOctalExample dto = new DecimalToOctalExample();      int decimal;      Scanner sc = new Scanner(System.in);       System.out.println("Please enter a decimal number: ");      decimal = sc.nextInt();      System.out.println("The octal number is : ");      int oct[] = dto.convertToOctal(decimal);      for(int a = x - 1; a > 0; a--)      {         System.out.print(oct[a]);      }      sc.close();   }}`

Output:

Please enter a decimal number: 644
The octal number is : 1204
