Passing Any Type As A Method Parameter [duplicate]

Question

I am trying to have a method that can take in ANY TYPE as a parameter (Object, int, boolean, ArrayList, etc.). Here is a very simple method to illustrate what it would be trying to do:

public void printAnything(Type arg0) {
    System.out.println(arg0);
}

And what I am asking is, what would replace Type in that method?

Answer 1

In your specific example, Object would fit well because PrintStream#println(Object obj) would print the string representation (using String#valueOf(Object)).

When you pass a primitive value, it will be automatically boxed into its wrapper type, e.g an int would be converted to java.lang.Integer which extends Object.
