Data known as parameters can be passed to the method. This block of code runs when the method is invoked. In simple terms, the method is a code block having a collection of statements to perform certain actions. While considering the definition of the term Method, Methods are considered as procedures associated with a class. So, let’s understand the Java method syntax to define our own Java method. To create our methods, we first need to understand the concepts and rules to create methods. These methods are called as User Defined methods. Methods Defined By UsersĪlong with the readymade standard library methods, a developer can create his/her method as well to perform a certain task. Some of the standard library methods we commonly use are Math library methods like Math.random(), Math.sqrt(), or String methods like equals () to compare two strings or concat () to join two strings. To consume these libraries in our Java code, a jar file called stdlib.jar needs to be added to the Java classpath.
