---

---

Description

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

Declaration

Following is the declaration for java.lang.Long.toOctalString() method

 public static String toOctalString(long i) 

Parameters

i − This is an long to be converted to a string.

Return Value

This method returns the string representation of the unsigned long value represented by the argument in octal (base 8).

Exception

NA

Getting Octal String Representation of a Positive long Value Example

The following example shows the usage of Long toOctalString() method to get the octal string representation of the specified long value. We've created a long variable and assigned it a positive long value. Then using toOctalString() method, we're printing the result.

 package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long i = 170L; System.out.println("Number = " + i); /* returns the octal string representation of the given number */ System.out.println("toOctalString = " + Long.toOctalString(i)); } } 

Output

Let us compile and run the above program, this will produce the following result −

 Number = 170 toOctalString = 252 

Getting Octal String Representation of a Negative long Value Example

The following example shows the usage of Long toOctalString() method to get the octal string representation of the specified long value. We've created a long variable and assigned it a negative long value. Then using toOctalString() method, we're printing the result.

 package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long i = -170L; System.out.println("Number = " + i); /* returns the octal string representation of the given number */ System.out.println("toOctalString = " + Long.toOctalString(i)); } } 

Output

Let us compile and run the above program, this will produce the following result −

 Number = -170 toOctalString = 37777777526 

Getting Octal String Representation of a Zero Value Example

The following example shows the usage of Long toOctalString() method to get the octal string representation of the specified long value. We've created a long variable and assigned it a zero value. Then using toOctalString() method, we're printing the result.

 package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long i = 0L; System.out.println("Number = " + i); /* returns the octal string representation of the given number */ System.out.println("toOctalString = " + Long.toOctalString(i)); } } 

Output

Let us compile and run the above program, this will produce the following result −

 Number = 0 toOctalString = 0
