Java Convert Binary to an Octal

Below Java programs converts any Binary Number to an Octal Number:
package net.sourcecodeexamples.java.Conversions; import java.util.Scanner; /**  * Converts any Binary number to an Octal Number  *  * @author https://www.sourcecodeexamples.net/  */ public class BinaryToOctal { /**  * Main method  *  * @param args Command line arguments  */ public static void main(String args[]) { try (Scanner sc = new Scanner(System.in)) { System.out.print("Input the binary number: "); int b = sc.nextInt(); System.out.print("Octal equivalent: " + convertBinaryToOctal(b)); } } /**  * This method converts a binary number to an octal number.  *  * @param binary The binary number  * @return The octal number  */ public static String convertBinaryToOctal(int binary) { String octal = ""; int currBit = 0, j = 1; while (binary != 0) { int code3 = 0; for (int i = 0; i < 3; i++) { currBit = binary % 10; binary = binary / 10; code3 += currBit * j; j *= 2; } octal = code3 + octal; j = 1; } return octal; } }

Output

Input the binary number: 1111 Octal equivalent: 17
