Does Java pass by reference or by value?



Java passes everything by value, and not by reference.

When passing an argument (or even multiple arguments) to a method, Java will create a copy and pass that to the method as arguments – and that is why it is called pass by value.

a variable of a class type stores an address of the object, and not the object itself.
Java manipulates objects 'by reference,' but it passes object references to methods 'by value.'
