what dose : and ? means in java

# Help me

Example:

```
int pointsScored = 21;
char gameResult = (pointsScored > 20) ? 'W' : 'L'; // W stands for Win, L stands for Lose
```

if pointsScored is bigger than 20 (which is 21), then gameResult becomes W, if not, L.

I hope I explained myself simple enough

Itâ€™s called **the ternary operator** and it is liked a condensed if statement.

Consider you have a boolean `expr`

and you want to set a variable to **1** if `expr`

is `true`

and to **-1** if it is `false`

. The syntax to do this is:

```
int ans = expr ? 1 : (-1);
```

If you already know if-statements you can also write this code as:

```
int ans = 0;
if(expr) {
ans = 1;
} else {
ans = -1;
}
```

You can for instance use it to quickly get the absolute value of a number:

```
int num = -34; // randomly chosen
int abs = (num < 0) ? (-num) : num;
```
