E.g., List list = // new ArrayList(); public List getItems(){...} This way, the implementation can ... |

18. reference type casting coderanch.comSure there are specific rules. If you want the nitty-gritty details you can read the Java Language Specification. In a nut shell, you must use a cast when you are assigning a variable of a general type to a more specific type. For example, if you want to assign a long value to an int or a int to a byte, ... |
19. Type casting coderanch.comThis is what the Java Language Specification says about assignment conversions. Assignment conversion occurs when the value of an expression is assigned (15.26) to a variable: the type of the expression must be converted to the type of the variable. Assignment contexts allow the use of an identity conversion (5.1.1), a widening primitive conversion (5.1.2), or a widening reference conversion (5.1.4). ... |
20. Doubt on Type casting coderanch.comA byte is a signed, 8-bit integer in Java, so it can hold values between -128 and 127. The Java compiler is smart. When you initialize a byte variable with a literal integer value, the compiler checks if it is in the range -128 to 127. So a statement like: byte b = 6; works without problems. If the literal integer ... |

26. Regarding type casting coderanch.comNote that this is not type-casting. You are constructing a new object. Type casting is for object references or primitives. For object references, you type cast when you have declared a reference as a superclass, but you know that the object it points to is actually of some subclass. For primitives, you type cast when you want to force the primitive ... |
27. Why this type of Cast isn't allowed? coderanch.comA lot of things are only obvious right after you know them. Don't stop asking questions!

If you need to assign a literal numeric value to a narrower type, and the value is outside that type's range, then you (the programmer) must supply an explicit cast.
