You can use those math operations with an assignment operator to make a
math operation and update the value of a variable in one fell swoop using
compound operators. These two lines of code all do the exact same thing:

doubleThis = doubleThis * 2;
doubleThis *= 2;

There's also shorthand syntax to increment and decrement integers by using
++ or -- . The following three lines of code all do the exact same thing:

countUp = countUp + 1;
countUp += 1;
countUp++;

And these lines of code all do the same thing as well:

countDown = countDown - 1;
countDown -= 1;
countDown--;

if Statements
Another new programming concept introduced in Example 3-2 is the if
statement, which you'll likely find yourself using a lot. The concept is fairly
simple: if something is true, then do something.
The syntax looks like this:

if (condition) {
execute this code if condition is true
}

There are a few different conditions you can test for, as laid out in Table 3-1 .
Table 3-1. Comparison operators

Operator Evaluates to True if…

x == y x is equal to y

x != y x is not equal to y

x < y x is less than y

x > y x is greater than y

x <= y x is less than or equal to y

x >= y x is greater than or equal to y

Let's take a look at a few simple examples of if statements:

int n = 10;

if (n > 10) {
