Java 'for loop' variables declared in the parameter list

Question

How do I write a 'for' loop that starts counting from the given 'start' number? Without the first statement in the loop, the code will result in an error. Writing 'start = 0;' starts the counting from 0. Thanks in advance!

You can leave the initial statement blank and just put a semicolon.

for(; start <= end; start++)

Just do:

for(int i = start; i <= end; i++){
    end--;
    System.out.print(start);
}

Although in actuality if you want your code to work you have to do:

for(int i = start; i <= end; i++){
    System.out.print(start);
}
