Question

So I was trying to print an array of ints in my program, and following these instructions What's the simplest way to print a Java array?

wrote the following code:

    int[] totals = //method that returns int array
    System.out.println(Arrays.toString(totals));

But it wont compile saying that

“method toString in class Object cannot be applied to given types.
required: no arguments
found: int[]
reason: actual and formal argument list differ in length”

Why does it do that? Do I not pass my array as an argument to toString? If not, how do I use toString?

Thank you!

Answer 1

method toString in class Object cannot be applied to given types. required: no arguments found: int[] reason: actual and formal argument list differ in length

May be you have a variable named Arrays, that’s why the compiler is complaining thinking that you are trying to invoke the Object.toString(), which doesn’t take any argument.

Try

 System.out.println(java.util.Arrays.toString(totals));
