Code for testing:
Public int [] getintarray () {response. write ("running"); return New int [] {0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };}

Test code of foreach:

Foreach (int x in this. getintarray () {response. Write (x );}

Running result: Running

For test code:

For (INT x = 0; x <this. getintarray (). length; X ++) {response. Write (x );}

Running result:

The above are the running results of the two types of code, which clearly shows the differences between for and foreach. If foreach is used, foreach is used.
