Print the integers from 1 to 20 using a while loop and the int counter variable x. Print only 5 integers per line. [Hint: When x % 5 is 0, print a newline character; otherwise, print a tab character.]

Here's the code to print the integers from 1 to 20 using a while loop and the int counter variable x, with 5 integers per line:

int x = 1;
while (x <= 20) {
    System.out.print(x);
    if (x % 5 == 0) {
        System.out.println();
    } else {
        System.out.print("\t");
    }
    x++;
}

Output:

1	2	3	4	5
6	7	8	9	10
11	12	13	14	15
16	17	18	19	20
