5 Different Ways of Printing an Array
for(int n: arr)
System.out.println(n+", "); |
for(int n: arr)
System.out.println(n+", ");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + ", ");
} |
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + ", ");
}
System.out.println(Arrays.asList(arr)); |
System.out.println(Arrays.asList(arr));
Arrays.asList(arr).stream().forEach(s -> System.out.println(s)); |
Arrays.asList(arr).stream().forEach(s -> System.out.println(s));
The Winner
Apparently, the first one is simple enough. If an array is multi-dimensional, i.e., it contains arrays as elements, we can use Arrays.deepToString() to print the array:
System.out.println(Arrays.deepToString(arr)); |
System.out.println(Arrays.deepToString(arr));
