The trick here is to use a map internally which handles the mapping of an integer (or whichever type you need) to its corresponding enum. This is done in a static method, which iterates through the values within the enum and adds them to the map.

radix tells the range of the number that we want to get, here we are using 10, which allows the range of 0 to 9.

We can convert double to int in java using typecasting. To convert double data type into int, we need to perform typecasting. Typecasting in java is performed through typecast operator (datatype). Here, we are going to learn how to convert double primitive type into int and Double object into int. The Integer class in Java belongs to the java.lang package, which means any class is free to use the methods in this class without importing any package. It implicitly extends the class Number, which is a direct subclass of Object. Number is an abstract class and acts as a superclass to BigInteger, BigDecimal, and most wrapper classes — Double, Integer, Short, Byte, Float and Long.

2019-11-27 · Ways to convert Double to Int in Java. As we all know, a Double primitive contains decimal digits. On conversion of these values to integers, the decimal digits get truncated, by rounding off the number to the nearest integer according to the method you choose. Java provides the following three ways to convert Double values to integer numbers:
