Question

What's the simplest way to print a Java array?

Answer 1

hey mate here's your answer

In Java, arrays don't override toString(), so if you try to print one directly, you get the className + @ + the hex of the hashCode of the array, as defined by Object.toString():

int[] intArray = new int[] {1, 2, 3, 4, 5};

System.out.println(intArray); // prints something like '[I@3343c8b3'

But usually we'd actually want something more like [1, 2, 3, 4, 5]. What's the simplest way of doing that? Here are some example inputs and outputs:

// array of primitives:

int[] intArray = new int[] {1, 2, 3, 4, 5};

//output: [1, 2, 3, 4, 5]

// array of object references:

String[] strArray = new String[] {"John", "Mary", "Bob"};

//output: [John, Mary, Bob]

Answer 2

The simplest and easiest way to print an Array in Java is by using toString( ) method of Arrays class in java.util package.
