Bro, a final variable is a constant or non-variable variable(it was a bit ironical). for ex. final int HOUSE_AREA = 5000; // Area of a house can't change int cost_per_sqrft = 3400: // Cost per sqr ft can change with time. another example. final int COLUMNS = 5 ; // No. of columns in a table is fixed. int ROWS = 10 ; // Rows can change one question that came into my mind when I was learning Java was - why we won't use explicit or raw integers directly. the answer is we can but it creates a messy code if same constant is used many times that's why we use Math.PI in place of its real value 3.14756848............. Code better , be best.
