outprint all weekdays(July)

Question

Hello, I want to outprint all the (31) weekdays of July, but I haven't been able to find the solution.
Here is my code:

package testPackage;

public class testClass {

public static void main(String[] args) {

System.out.println("\tDay");
String[] arr = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"};

int july = 31;

for(int counter=1;counter<july;counter++) {
System.out.printf("%n"+ counter + "\t" + arr[counter]);
}
}

}

Output:

Day

1 Mon
2 Tue
3 Wed
4 Thu
5 Fri
6 SatException in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7
at testPackage.testClass.main(testClass.java:14)

Answer 1

Your counter goes beyond 6, which is the maximum you can use as an index in arr. Use counter%7 so your index wraps around to zero.
