java.lang.Long toOctalString(long i)


The Long.toOctalString(long i) java method returns a string representation of the long argument as an unsigned integer in base 8.

The unsigned long value is the argument plus 264 if the argument is negative; otherwise, it is equal to the argument. This value is converted to a string of ASCII digits in octal (base 8) with no extra leading 0s.

The value of the argument can be recovered from the returned string s by calling Long.parseUnsignedLong(s, 8).

If the unsigned magnitude is zero, it is represented by a single zero character ‘0’ (‘u0030’); otherwise, the first character of the representation of the unsigned magnitude will not be the zero character.

Make a note that the toOctalString() method of Long class is static thus it should be accessed statically which means the we would be calling this method in this format:

Long.toOctalString(method args)

Non static method is usually called by just declaring method_name(argument) however in this case since the method is static, it should be called by appending the class name as suffix. We will be encountering a compilation problem if we call the java toOctalString method non statically.

Method Syntax

public static int toOctalString(long i)

Method Argument

Data Type Parameter Description
long i a long to be converted to a string.

Method Returns

The toOctalString(long i) method of Long class returns the string representation of the unsigned long value represented by the argument in octal (base 8).


Requires Java 1.0.2 and up

Java Long toOctalString(long i) Example

Below is a simple java example on the usage of toOctalString(long i) method of Long class.


 * This example source code demonstrates the use of  
 * toOctalString(long i) method of Long class

public class LongToOctalStringExample {

	public static void main(String[] args) {
		// declare a new long value
		Long val = 88L;
		// get the toOctalString() method result
		String result = Long.toOctalString(val);
		// print the result
		 * This method will yield the same result as toString() method
		 * if the radix use is 8


Sample Output
