How to print Arrays to the console in Java #java #flashcard

gistfile1.md

Use Arrays.toString(arr) or Arrays.deepToString(arr) from java.util.Arrays.

int[] intArray = new int[] {1, 2, 3, 4, 5};
String[] strArray = new String[] {"John", "Mary", "Bob"};

System.out.println(Arrays.toString(intArray));
System.out.println(Arrays.toString(strArray));

In Java 8 we can also use lambda expressions.

Arrays.stream(intArray).forEach(System.out::println);
Arrays.stream(strArray).forEach(System.out::println);
