How can I print an array easily? [duplicate]

Question

I am currently working with arrays, and everytime I need to print one I do a for loop.

System.out.print("[");
for(int i = 0; i < arr.length; i++){
    System.out.print(arr[i] + ", ");
}
System.out.println("]");

This seems like a feature that would be built into java (I am using java). Is there a built in way to print arrays?

Answer 1

You could use: Arrays.toString(arr) for normal arrays and/or Arrays.deepToString(arr) for arrays within arrays. Both these methods return the string representation of the array.

See the Arrays docs for more.
