Primitive types and objects are very different things in Java, and you can't automatically cast between the two or use them interchangeably. As an alternative, the java.lang package includes classes that correspond to each primitive data type: Float, Boolean, Byte, and so on. Most of these ...
By the way, all Java objects are polymorphic because each object is anObjectat least. We can assign an instance ofAnimalto the reference variable ofObjecttype and the compiler won’t complain: Object object = new Animal(); That’s why all Java objects we create already haveObject-specific ...
Note.When we try to type conversion of double to a byte in Java implicitly, it causes an error the byte data type takes 1 byte of memory, and double takes 8 bytes of memory. Assigning 8 bytes of memory to 1 byte of memory requires explicit casting. byte to double conversion in Java ...

non-const object to const object (as in Item 3), int to double, etc.). It can also be used to perform the reverse of many such conversions (e.g., void* pointers to typed pointers, pointer-to-base to pointer-to-derived), though it cannot cast from const to non-const objects. (...
Associative arrays converts into objects with the keys as property names and values as property values.Example Converting Arrays into Objects: $a = array("Volvo", "BMW", "Toyota"); // indexed array $b = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43"); // associative array $a...
Syntax for casting in OO, is like this. * References to the objects data: r_account type ref to lcl_account. data: r_checking type ref to lcl_checking. * Is the account, a checking account? r_checking ?= r_account. You will learn this when you get to ABAP OO. Regards, Rich ...
