Java programing:

1.Show the general if - else if - else ladder.

2. Show the for statement for a loop that counts from 2000 to 100 by -4.

3. Is the following fragment valid? Why or why not? for(int i = 0; i < num; i++) sum += i; count = i;

4. What does the following fragment print? for(int i = 0; i < 10; i++) { System.out.print(i + " "); if(i%2 == 0) continue; System.out.println(); }
