declare an integer in java

int number = 999;

This code declares an integer (whole number) variable with the name “number” and assigns the value 999 to it. An int is used in programming to represent whole numbers, while other data types such as float and double can also be used to represent decimal numbers.

To declare an integer, we start with the keyword “int”, followed by the name of the variable (“number”). We then assign a value to the variable using the assignment operator (=). Finally, the value of the variable is specified - in this case, 999. This value can be changed in the future by simply assigning a different number to the variable.
