In Java, parameter passing is by value. The reason is: When a variable is passed as a parameter to a method, the value of the variable is actually passed to the method.

In Java, parameter passing is by value.
This means that when you pass a variable as a parameter to a method, you are actually passing the value of the variable to the method.
If a basic data type is passed, modifications to the parameter within the method will not affect the value of the original variable. If an object reference is passed, modifications to the object pointed to by the parameter within the method will affect the object pointed to by the original variable.
However, if the parameter is reassigned within the method, the value of the original variable will not be affected.
Therefore, although parameter passing in Java is by value, for object references, since the value of the reference is passed, it looks like passing by reference.
