Let us learn octal to decimal conversion in java.

The conversion from octal to decimal takes place with the help of Integer wrapper class. This class provides a method Integer.parseInt(String s, int radix) which converts binary, hexadecimal and octal number to decimal number.

The parameters in the above method namely “String s” and “int radix” indicates

String s – binary, hexadecimal and octal number,

int radix – in what base the first argument is represented.

The method Integer.parseInt(String s, int radix) size is less than 32-bits. However, the size greater than 32-bits will throw an unchecked runtime java.lang.NumberFormatException.
