The following code uses final and blank final local variables in the test() method.
public class Main { public static void main(String[] args) { int x = 0; // A variable final int y = 10; // A final variable. Cannot change y here onward final int z; // A blank final variable // We can read x and y, and modify x x = x + y; /* We cannot read z here because it is not initialized yet */ /* Initialize the blank final variable z */ z = 1; /* Can read z now. Cannot change z here onwards */ x = x + z; } }
