How to convert an int to a double type in Java?
In Java, you can convert an int variable to a double variable by assigning the int variable directly to the double variable. For example:
int intValue = 10;
double doubleValue = intValue;
In the example above, the variable intValue of type int is converted to a variable doubleValue of type double. Java will automatically convert int type to double type, without any additional steps required.
