The parameter passing mechanism in Java is pass-by-value example: publicclassTest{publicstaticvoidmain(String[] args){ testa a =newtesta(); a.a=1; testa b =newtesta(); b.a =13; a.next = b; fool(a); System.out.println(a.a); System.out.println(a.next); }staticvoidfool(testa ...
Java is officially always pass-by-value. The question is, then, “what is passed by value?” As we have said in class, the actual “value” of any variable on the stack is the actual value for primitive types (int, float, double, etc) or the reference for reference types. That is,...
因此如果面试时有人问你,java是pass by value还是pass by reference。完整的回答应该如下: java is pass by value, and the value is copy of the reference of object, which still points to the object.

Is Java pass by reference or pass by value?Brian L. Gorman
Java is passed by value and not pass-by-reference. If it had been pass-by-reference, we should have been able to C like swapping of objects.
Pass by reference: An alias or reference to the actual parameter is passed to the method. The method accesses the actual parameter. Often, the confusion around these terms is a result of the concept of theobject referencein Java. Technically, Java is always pass by value, because even though...
Java is a pass-by-value language. Even Objects are still pass-by-value behind the scenes. Objects simulate pass-by-reference by passing the value of their reference.https://stackoverflow.com/questions/40480/is-java-pass-by-reference-or-pass-by-value ...
值传递(pass by value)是指在调用函数时将实际参数复制一份传递到函数中,这样在函数中如果对参数进行修改,将不会影响到实际参数。 引用传递(pass by reference)是指在调用函数时将实际参数的地址直接传递到函数中,那么在函数中对参数所进行的修改,将影响到实际参数。
Java is Pass By Value and NOT Pass By Reference First of all we should understand what is meant by "pass by value" or "pass by reference".Pass by Value: The method parameter values are copied to another variable and then the copied object is passed, that’s why it’s called pass ...
