Question

every code should be in java Program 1: Write a while loop that sums the integers from 1 to 10, excluding 3 and 6. Print the sum. [Hint: Use logical operators] Program 2: Write a for loop that attempts to display the numbers from 1 to 10, but terminates when the control variable reaches the value 6. Program 3: Write a do...while loop that prints the integers from 10 to 0, inclusive.

Answer 1

//TestCode1.java
public class TestCode1  {
    public static void main(String[] args) {
        int i = 1, sum = 0;
        while(i<=10){
            if(i!=3 && i!=6)
                sum += i;
            i += 1;
        }
        System.out.println(sum);
    }
}
