Java Function Types
Java is an object-oriented programming language that offers various types of functions to perform different tasks and operations. These functions can be categorized into several types, each serving a specific purpose in programming. One of the types of functions in Java is the main function. The main function serves as the entry point for a Java program. It is the starting point where the program execution begins. Another type of function in Java is the user-defined function. User-defined functions are created by the programmer to perform a specific task or set of operations. These functions can be called within the program to execute the defined task.
They provide a way to modularize code and break it down into smaller, reusable components, making the code more organized and manageable. Additionally, Java offers built-in functions known as standard library functions. These functions are provided by the Java language itself and can be directly used in a program without any need f or defining them. Standard library functions in Java include mathematical functions like Math.sqrt() for calculating the square root of a number, and String functions like .substring() for extracting a substring from a string.
