How can I cast int to enum in java?

Question

Aryan Kumar · Answer

Sure, here are two ways to cast int to enum in Java:

Using the .valueOf() method:

Java

enum MyEnum {
  VALUE1,
  VALUE2,
  VALUE3
}

int myInt = 1;

// Cast the int to an enum using the valueOf() method.
MyEnum myEnum = MyEnum.valueOf(myInt);

In this example, the myInt variable is an int that has the value 1. The myEnum variable is an enum that is initialized to the value of VALUE1. The MyEnum.valueOf(myInt) method casts the myInt variable to an enum.

Using the instanceof operator:

Java

enum MyEnum {
  VALUE1,
  VALUE2,
  VALUE3
}

int myInt = 1;

// Check if the int is an instance of the enum.
if (MyEnum.class.isInstance(myInt)) {
  // Cast the int to an enum.
  MyEnum myEnum = (MyEnum) myInt;
}

In this example, the myInt variable is an int that has the value 1. The MyEnum.class.isInstance(myInt) method checks if the myInt variable is an instance of the MyEnum enum. If it is, then the myEnum variable is casted to an enum.

Which method you use depends on your specific needs. If you need to cast an int to an enum and you don't need to do any further processing on the enum value, then the valueOf() method is a good option. If you need to do further processing on the enum value, then the instanceof operator is a good option.
