<\/span><\/h2>\nPass by value means that when we pass a variable as an argument to a method in Java, a copy of the value is made, and this copy is then passed to the method. Any changes made to the parameter inside the method do not affect the original variable outside the method.<\/b><\/p>\n
To illustrate this concept further, let’s consider an example:<\/p>\n
“`java
\npublic class PassByValueExample {
\n public static void main(String[] args) {
\n int x = 10;
\n modifyValue(x);
\n System.out.println(“Value of x after method call: ” + x);
\n }<\/p>\n
public static void modifyValue(int value) {
\n value = value + 5;
\n System.out.println(“Value inside the method: ” + value);
\n }
\n}
\n“`<\/p>\n
In the above code, the main method declares an integer variable `x` and assigns it a value of `10`. We then call the `modifyValue` method, passing in the value of `x`. Inside the `modifyValue` method, we add `5` to the parameter `value`, resulting in `15`. However, when we print the value of `x` after the method call, it remains unchanged at `10`.<\/p>\n
This behavior is due to pass-by-value, as a copy of the value of `x` is passed to the `modifyValue` method. Therefore, any modifications inside the method do not affect the original variable itself.<\/p>\n
Pass by value is consistent throughout Java, whether the argument is a primitive type (such as `int`, `double`, `boolean`) or a reference type (such as objects).<\/p>\n
