11 lip 2022 · Java brings various Streams with its I/O package that helps the user to perform all the input-output operations. These streams support all the types of objects, data-types, characters, files etc to fully execute the I/O operations.
This tutorial would cover package java.lang, which provides classes that are fundamental to the design of the Java programming language. The most important classes are Object, which is the root of the class hierarchy, and Class, instances of which represent classes at run time.
FUNCTION. Declares a user-defined function. Syntax. FUNCTIONfunction_name [ ( arguments ) ] [ STATIC ] … function_name = expression … END FUNCTION. Notes. function_name is the name of the user-defined function. The name can end with a type-declaration character (%, &, !, # or $) to indicate the type of value it returns.
When a function is used in an expression, it calls a predetermined operation that is to be performed on its operands. BASIC has two types of functions: “intrinsic” functions, such as SQR (square root) or SIN (sine), which reside in the system, and user-defined functions that are written by the programmer.
