main is predeclared and user defined.
No. It is a user defined function which the person who is creating the java class has to code by himself.
1.user defined packages 2.predefined packages
programming syntax is defined as a predefined pattern in which the program is written. for example:- the programming syntax in c is as: #include<headerfile or prototype> as per need. global declaration. main function or(void main) { body of coding; //comments } user defined functions() { coding; //comments }
What is the difference between predefined function and user defined functions
Predefined functions are functions that have been written and we can use them in our C++ statements. But we must know how to use each of these predefined functions.
A predefined structure or, more generally, a predefined type, is a type that is defined internally by the compiler implementation. For instance Microsoft's implementation includes predefined runtime information and GUID structures, amongst other predefined types such as size_t. These types are built in to the compiler itself, so you won't find them in a header file. By contrast, user-defined structures (types) are those you define yourself, or are provided for you by a third party.
Java Classpath is a parameter that tells the Java Virtual Machine or the Java Compiler, where to search for user-defined classes and packages on a computer.
User Group
Actually user defined data type made by user like array,structure,union,pointer. the data type which is define by user or programer according to his need is called user define data type and also called the programer define data type........
The term user-defined really means programmer-defined when referring to programming. An user-defined array is therefore an array that the programmer has declared, rather than one that is provided by a third party or is built-in to the language. In essence, any array you yourself declare is an user-defined array. The following are examples of user-defined arrays: int x[10]; // static array of 10 integer elements. Allocated at compile time. int* y = new int [5]; // dynamic array of 5 integer elements. Allocated at runtime.
A user-defined object is an instance of a user-defined type, typically a class, or an enum.
A predefined set of permissions and rights assigned to user accounts is often called the terms of service or service terms. Although they are virtually everywhere they are largely ignored.
