Aug 7, 2024 · Methods in Java are reusable pieces of code that perform specific tasks. They help you break down complex programs into smaller, manageable parts. Here's why methods are so useful:
Feb 29, 2024 · Methods are essential for organizing Java projects, encouraging code reuse, and improving overall code structure. In this article, we will look at what Java methods are and how they work, including their syntax, types, and examples. Here's what we'll cover: What are Java Methods? Types of Access Specifiers in Java – Public (public)
A method is a block of code which only runs when it is called. You can pass data, known as parameters, into a method. Methods are used to perform certain actions, and they are also known as functions. Why use methods? To reuse code: define the code once, and use it many times.

- What Are The Advantages of Using Methods?
The syntax to declare a method is: Here, 1. 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. 2. methodName - It is an identifierthat is used to refer to the particular method in a program. 3. ...
In the above example, we have declared a method named addNumbers(). Now, to use the method, we need to call it. Here's is how we can call the addNumbers()method.
Output In the above example, we have created a method named addNumbers(). The method takes two parameters a and b. Notice the line, Here, we have called the method by passing two arguments num1 and num2. Since the method is returning some value, we have stored the value in the resultvariable. Note: The method is not static. Hence, we are calling th...
A Java method may or may not return a value to the function call. We use the return statementto return any value. For example, Here, we are returning the variable sum. Since the return type of the function is int. The sum variable should be of inttype. Otherwise, it will generate an error.
A method parameter is a value accepted by the method. As mentioned earlier, a method can also have any number of parameters. For example, If a method is created with parameters, we need to pass the corresponding values while calling the method. For example,
The standard library methods are built-in methods in Java that are readily available for use. These standard libraries come along with the Java Class Library (JCL) in a Java archive (*.jar) file with JVM and JRE. For example, 1. print() is a method of java.io.PrintSteam. The print("...")method prints the string inside quotation marks. 2. sqrt() is ...
1. The main advantage is code reusability. We can write a method once, and use it multiple times. We do not have to rewrite the entire code each time. Think of it as, "write once, reuse multiple times".
