You can tell Java that a number is in octal (base 8) by prefixing it with a zero.
In the example below, the variable octal_77 is assigned the value 077 i.e. octal 77. The program then displays the value in decimal (base 10).
In the example below, the variable octal_77 is assigned the value 077 i.e. octal 77. The program then displays the value in decimal (base 10).
UNIX > cat prog21.java
public class prog21
{
public static void main (String args[])
{
int octal_77 = 077;
System.out.println
("octal 77 = " + octal_77);
}
}
UNIX > javac prog21.java
UNIX > java prog21
octal 77 = 63

You can check the result yourself by converting octal 77 to decimal (base 10) like this:
octal 77 = (in decimal or base 10) (7 x 8) + 7 = 63
