Logic Practice: Equivalent Conditionals (beginner)

equiv-conditionals.java

// all three of the below code snippets are equivalent!

// #1: If you notice the body of your 'if' is empty but your else has code, then convert it to #2
if(A && B)
{
    // do nothing
}
else
{
    doSomething();
}

// #2: By negating the condition, we get rid of the empty 'if' and move the else into the if.
if(!(A && B))
{
    doSomething();
}

// #3 - We can also distribute the ! operator- just remember to reverse the &&! This is called DeMorgan's Law.
if(!A || !B)
{
    doSomething();
}
