Comment

When we declare a final variable without giving any initial value,

then it is called blank final variable.

class Test
{
    final public int i;
 
    Test(int val)    {  this.i = val;  }
 
    Test()
    {
        // Calling Test(int val)
        this(10);
    }
 
    public static void main(String[] args)
    {
        Test t1 = new Test();
        System.out.println(t1.i);
 
        Test t2 = new Test(20);
        System.out.println(t2.i);
    }
}
