<lang java>Integer number = Integer.valueOf(stringNum, base);</lang>
The base here has the same restrictions as the <tt>Scanner</tt> example. A similar method is available in the <tt>Long</tt> class. Use no second argument for base 10.

The <tt>hex()</tt> function parses hexadecimal strings. The <tt>oct()</tt> function parses octal strings, as well as hexadecimal, octal, or binary strings with the appropriate prefix ("0x", "0", and "0b", respectively).
<lang perl>my $dec = "0123459";
my $hex_noprefix = "abcf123";
my $hex_withprefix = "0xabcf123";
my $oct_noprefix = "7651";
my $oct_withprefix = "07651";
my $bin_withprefix = "0b101011001";
print 0 + $dec, "\n"; # => 123459
print hex($hex_noprefix), "\n"; # => 180154659
print hex($hex_withprefix), "\n"; # => 180154659
print oct($hex_withprefix), "\n"; # => 180154659
print oct($oct_noprefix), "\n"; # => 4009
print oct($oct_withprefix), "\n"; # => 4009
print oct($bin_withprefix), "\n"; # => 345
# nothing for binary without prefix
