(Solved) Is Java “pass-by-reference” or “pass-by-value”?

Introduction

Java is a popular programming language used by developers around the world. One of the most common questions asked about Java is whether it is a “pass-by-reference” or “pass-by-value” language. This article will explain the difference between the two and provide an answer to the question. It will also discuss the implications of the answer and how it affects the way Java is used.

Solution

Java is pass-by-value.

Java is a pass-by-value language, meaning that when an argument is passed to a method, a copy of the argument’s value is passed to the method. This means that any changes made to the argument within the method have no effect on the argument outside of the method. This is different from pass-by-reference, where a reference to the argument is passed to the method, and any changes made to the argument within the method are reflected outside of the method.

In Java, primitive data types (such as int, double, and char) are always passed by value. Objects, on the other hand, are passed by reference. This means that when an object is passed to a method, a reference to the object is passed to the method. Any changes made to the object within the method are reflected outside of the method.

In summary, Java is a pass-by-value language, meaning that primitive data types are always passed by value, and objects are passed by reference. This means that any changes made to an argument within a method have no effect on the argument outside of the method, unless the argument is an object.
