Java Taskbook Level 3.6
Given an array of integers, output to the console numbers that consist of more than three digits.
Given an array, output every fifth element to the console.
Given an array of strings, leave in this array only those strings that end with ".html".
Given a number, for example, like this:
int num = 12345;
Check that all digits of this number are greater than zero.
Three arrays are given:
int[] arr1 = [1, 2, 3];
int[] arr2 = [4, 5, 6];
int[] arr3 = [7, 8, 9];
Combine these arrays into one:
int[] {1, 2, 3, 4, 5, 6, 7, 8, 9}
Given a variable with a number:
int num = 5;
Make a string containing as many zeros as specified in the variable. In our case, we get the following string:
"00000"
