Java for loop use method

The For loop in Java has a--foreach notation (typically used only to traverse the entire array, without worrying about cross-border issues).

1.1) General wording:

[Java]View Plaincopyprint?

2. Package foreach.main.sn;
6. Public class Foreach {
10. public static void Main (string[] args) {
12. int[] arr = {1,2,3,4,5};
14. For (int i = 0; i < arr.length; ++i) {
16. System.out.println (Arr[i]);
18. }
20. }
22. }

1.2) foreach notation: (Note that the T here is a temporary variable value that holds the array value that is currently traversed and cannot be traversed if you need to change the value of the array)

[Java]View Plaincopyprint?

2. Package foreach.main.sn;
6. Public class Foreach {
10. public static void Main (string[] args) {
12. int[] arr = {1,2,3,4,5};
14. For (int t:arr) {
16. System.out.println (t);
18. }
20. }
22. }

2) Iterate through the two-dimensional array using foreach:

2. Package foreach.main.sn;
6. Public class Foreach {
10. public static void Main (string[] args) {
14. int[][] arr2 = {{1,2,3},{4,5},{6,7,8}};
18. For (int t1[]: arr2) {
20. For (int t2:t1) {
22. System.out.print (T2);
24. }
26. System.out.println ();
28. }
30. }
32. }
