static blank final variable
A static final variable
that is not initialized at the time of declaration is known as static blank
final variable. It can be initialized only in static block.
/**
* static blank final variable must be
initialized in static block.
* Otherwise there will compile time error.
*/
public class Solution {
//static blank final variable
static final int staticFinal;
public Solution() {
// The final field
Solution.staticFinal cannot be assigned
// staticFinal=50;
}
static {
staticFinal=50;
}
public static void main(String args[]){
System.out.println("static final blank:"
+Solution.staticFinal);
}
}
Output: static final blank:50
If you will assign in the
constructor, there will be error “The final field staticFinal
cannot be assigned” at compile time.
