Let’s say we have 3 arrays of following tetromino letters: J, L, O. Tetromino J is a 4 member long array (J,J,J,J), signifying the number of positions J block can take. L tetromino is also a 4 member long array and O is a square tetromino that has only one position (1 member long array). How do we calculate the total number of all unique n-letter long permutations, without programmatically permuting through them? [Read more…]
Java offers eight primitive data types which are not always adequate to store data of all types. There are situations when the specific data type does not fit into any of the primitive data types offered by Java. Thus it is essential to understand the boundaries and restrictions of the primitive data types in Java. In this article, I demonstrate a couple of the scenarios in which the Java data types are not sufficient enough and require substitute approach.
