what’s the simplest way to print a java array?

Examples:

• Simple Array:
  

  1 2	String[] array = new String[] {"John", "Mary", "Bob"}; System.out.println(Arrays.toString(array));

Output:

1

[John, Mary, Bob]

• Nested Array:
  

  1 2 3 4

  String[][] deepArray = new String[][] {{"John", "Mary"}, {"Alice", "Bob"}}; System.out.println(Arrays.toString(deepArray)); //output: [[Ljava.lang.String;@106d69c, [Ljava.lang.String;@52e922] System.out.println(Arrays.deepToString(deepArray));

Output:

1

[[John, Mary], [Alice, Bob]]

• double Array:
  

  1 2	double[] doubleArray = { 7.0, 9.0, 5.0, 1.0, 3.0 }; System.out.println(Arrays.toString(doubleArray));

Output:

1

[7.0, 9.0, 5.0, 1.0, 3.0 ]

• int Array:
  

  1 2	int[] intArray = { 7, 9, 5, 1, 3 }; System.out.println(Arrays.toString(intArray));

Output:

1

[7, 9, 5, 1, 3 ]
