Arguments in Java are always passed-by-value. During method invocation, a copy of each argument, whether its a value or reference, is created in stack memory which is then passed to the method.

Does Java pass by reference by default?

Java is officially always pass-by-value. That is, for a reference variable, the value on the stack is the address on the heap at which the real object resides. When any variable is passed to a method in Java, the value of the variable on the stack is copied into a new variable inside the new method.

How do you pass a value by reference in Java?

relative reference
By default, a cell reference is a relative reference, which means that the reference is relative to the location of the cell. If, for example, you refer to cell A2 from cell C2, you are actually referring to a cell that is two columns to the left (C minus A)—in the same row (2).

What is a reference in Java?

A reference is an address that indicates where an object’s variables and methods are stored. You aren’t actually using objects when you assign an object to a variable or pass an object to a method as an argument. You aren’t even using copies of the objects. Instead, you’re using references to those objects.

Why Java is strictly pass by value?

But Java uses only call by value. It creates a copy of references and pass them as value to the methods. If reference contains objects, then the value of an object can be modified in the method but not the entire object.

What is the difference between .equals and == in Java?

In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects. If a class does not override the equals method, then by default, it uses the equals(Object o) method of the closest parent class that has overridden this method.

What is pass-by-reference in Java with example?
