Java Long toOctalString() Method
Java toOctalString()
method is the part of the Long
class of the java.lang
package. This method is used to return the octal equivalent of the base 8 of the value passed as an unsigned long as a String.The unsigned long
value is the argument plus 2^64 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 0
s.
Syntax:
public static String toOctalString (long i)
Parameters:
The parameter passed is the long value of which the string representation of the equivalent octal of base 8 is to be returned.
Returns:
Returns the String representation of the parameter passed as equivalent base 8 octal value.
Example 1:
Here, a positive and a negative number is taken for a better understanding of the method.
import java.lang.Long;
public class StudyTonight
{
public static void main(String[] args)
{
long i = 284L;
long j = -56L;
System.out.println("Actual number is = " + i);
System.out.println("Octal equivalent is = " + Long.toOctalString(i));//returns the long value in octal base 8 as a string
System.out.println("Actual number is = " + j);
System.out.println("Octal equivalent is = " + Long.toOctalString(j)); //returns the long value in octal base 8 as a string
}
}
Actual number is = 284
Octal equivalent is = 434
Actual number is = -56
Octal equivalent is = 1777777777777777777710
Example 2:
Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent output.
import java.util.Scanner;
public class StudyTonight
{
public static void main(String[] args)
{
try
{
System.out.print("Enter the Number = ");
Scanner sc = new Scanner(System.in);
long i = sc.nextLong();
System.out.println("Actual Number is = " + i);
System.out.println("Octal representation is = " + Long.toOctalString(i)); //returns the long value in octal base 8 as a string
}
catch(Exception e)
{
System.out.println("Invalid Number");
}
}
}
Enter the Number = 933
Actual Number is = 933
Octal representation is = 1645
**************************************
Enter the Number = -794
Actual Number is = -794
Octal representation is = 1777777777777777776346
**************************************
Enter the Number = 0x445
Invalid Number
