Iteration in Programming

What happens to the value of "i" after each iteration in a standard for loop structure such as for(int i = 0; i < 10; i++)?

Given this code segment:

java  
int result =0;
for (int j=10; j>0;j--){
    if(j%3==0){
        result+=j;
    }
}

Which change will make result hold double its original final value after execution?

When would you choose a while loop over a for loop?

In a decrementing for-loop structured as

java 
for(int x=n;x>0;x--){
//body //
}```
Which modification ensures that exactly half the numbers from N down to zero are processed?

How many times will the following for loop execute its body if it starts with j equals zero?

java
for(int j=0; j <20; j+=5){
    // Body of loop here   
}```

What is the time complexity of a nested for loop where the outer loop runs n times and the inner loop runs n/2 times?

Which method would you use to determine the number of elements in an ArrayList named 'myList'?

If you need to ensure that an instance of your 'House' class always has an 'Address', what technique would best enforce this relationship without inheriting from 'Address'?

What type of loop should you use when you need to repeat an action a fixed number of times?

In Java, which of these data types can store decimal numbers?
