![]() (For example, a radix of 10 converts from a decimal number, 8 converts from octal, 16 from hexadecimal, and so on. Since parsing a String representation of a number is such a common thing to do, the Integer and Long classes also provide the static methods Integer.parseInt(). I tried to convert using Integer.parseInt, but it throws an exception. If we try to convert a string that is not a number(the content of the string is not a number), we will get NumberFormatException which is a runtime. If not NaN, the return value will be the integer that is the first argument taken as a number in the specified radix.
