Methods can be accessed in two ways: by value and by reference. Calling a method by value means passing a value as a parameter. Calling a method by reference means passing a reference (the variable’s location) as a parameter. Primitive data types (int, float, double, boolean, char, and so on) are always passed as values in Java, while non-primitive data types<\/a> (class, object, array, string, and interface) are always passed as references. This article will go over call by value in Java and call by reference in Java.<\/p>\n In Java, call by value refers to calling a method by passing the value in the parameter. In Java, call by value passes a copy of the variable to the method, so all changes are reflected only in that method; thus, no changes are reflected in the main method. This is the main difference between call by value in java and call by reference in java. When we pass a variable with primitive data types, it is considered a call by values in Java, so any changes to the variable will not be reflected in the caller’s scope.<\/p>\nCall by Value in Java<\/h2>\n
