I suggest writing out the rules that you want to determine what gets printed out. If you can't explain it in English (in a list of rules, not vague descriptions or examples), then you won't be able to write it in code.
Hint: You can have two if statements, one after the other, without using the else keyword. Something like:
if(x > 0){
System.out.println("X is greater than zero!");
}
if(x > 10){
System.out.println("X is greater than ten!");
}
If x is, for example, 15, then both print statements will be triggered. If x is 5, only the first one will be triggered.
