The difference between call by value and call by reference in Java

Question

I’m a little confused about the call by value and call by reference parts in Java. I hope someone with expertise can give me some advice or recommend some good articles or blogs. Thanks.

Answer 1

Call by value is easy to understand. The value of the basic data type is allocated on the stack. What is called and modified is the value on the stack.
Call by reference. To be precise, it should be call by address reference. What is called is the address reference. , which is the address on the heap.

Answer 2

Java is all about call by value, but when calling a function, if it is a primitive type, a copy of the original type address is passed, and if it is a reference type, a copy of the reference type address is passed.
