java 0x

"0x" is a prefix for hexadecimal numbers in Java. In Java, if an integer value starts with 0x or 0X, it means it is a hexadecimal number.

For example, the following code fragment assigns the integer 10 to the variable x:

int x = 0xA;

In this example, 0xA is a hexadecimal number whose decimal value is 10. Therefore, the value of x will be 10.

The integer types supported in Java include byte, short, int, long and other types. These types can be initialized and manipulated with hexadecimal values.
