Need to find what could be the potential problem in this

I have written a code. A part of which will do a decimal to octal transformation.

The function will take an Integer and convert it to corresponding octal number but return the result as String and not as number.

Code :

---

class Foo {
public static String dec_2_octal( int value) {
StringBuilder ret = new StringBuilder();
for(int i=0; i<31; i+=3) {
ret.append((value & 7<<i) >> i);
if( value <= (1<<(i+3))-1) break;
}
return ret.reverse().toString();
}
}

---

Can any one point out what could the potential problem in this program???
What I want to know, if this logic works??? or it may crash in some scenario??

Thanks in advance.

Hello eternity007!
You can use the Integer.toOctalString(int) method to accomplish your requirements , or at least test your code with it (btw I tested it and it seems to work properly).
