There is also a way to iterate through the string for the For loop

Traverse the character C so that it equals each character in the string array chars. Then run the following statement when C is assigned a value of chars inside all characters after each. Will exit this loop.

Usually we iterate over a string array with

for (int i=0;i<array.length;i++) {

Array[i];

}


In fact, using for (String C:valuearray) is more convenient

Where Valuearray is an array of strings, and C is a string variable in the array, direct access can

char[] CArray = Num.tochararray (); for (char c:carray) {int key = (int) c;if (!this.clicknum (key-48)) {return false;} Sleep.sleepseconds (2);}
