Examples Of Java Programs Using Methods
In this article, we will learn and prepare for Interviews using Java Programming Examples. From basic Java programs like the Fibonacci series, Java Methods Programs. This section unlocks the secrets of methods, the building blocks of reusability in object-oriented programming. Here, you'll embark on a hands-on journey, crafting and wielding
Java methods are defined blocks of code that perform a particular task. They consist of a method signature, which includes the method name and parameters, followed by a body containing executable statements. For example public int addint a, int b return a b In this example, the method add takes two integer parameters and returns their

Example Explained. myMethod is the name of the method static means that the method belongs to the Main class and not an object of the Main class. You will learn more about objects and how to access methods through objects later in this tutorial. void means that this method does not have a return value. You will learn more about return values later in this chapter
Default Use for helper methods or components specific to a package. Protected Use for shared functionality among subclasses, while restricting access from outside the inheritance hierarchy. Types of Methods. In Java, methods can be categorized in two main ways 1. Predefined vs. User-defined
With the help of examples, we will learn about Java methods, define them, and utilize them in Java programs in this article. A method is a piece of code that accomplishes a specific goal. Generally, a method is a collection of statements or statements organized together to conduct a particular task or action. Example Using Methods in Java
Declaring a Java Method. The syntax to declare a method is returnType methodName method body Here, returnType - It specifies what type of value a method returns For example if a method has an int return type then it returns an integer value. If the method does not return a value, its return type is void. methodName - It is an identifier that is used to refer to the particular method
Method Body Contains the logic or operations performed by the method. Types of Methods in Java. Predefined Methods These are built-in methods provided by Java, such as Math.sqrt or System.out.println. User-Defined Methods These are methods created by the programmer to perform specific tasks. Creating and Using Methods Defining a Method
Write a Java method to count the number of digits in an integer with the value 2. The integer may be assumed to be non-negative. Expected Output Input a number 12541 1 Click me to see the solution. 18. Check Consecutive Integers. Write a Java method that accepts three integers and checks whether they are consecutive or not. Returns true or false.
In this tutorial, we will discuss Java float and the floating-point types with details like width, range, size, and the usage example Even though float in Java is a simple concept, we have included all the necessary examples and programs that will be sufficient to make you understand the tutorial
