# A clever way to replace `Math` functions
You can shorten `if-else` statements through the `a?b:c` syntax, where `a` is the statement of `if`, `b` is the result of `if`, and `c` is the result of `else`.
<pre><code>static void main(String[]a){
	int i = 95;
~~	System.out.print(i>0?"positive":"negative");~~
}
</code></pre>

With this, you can take out the following functions from `java.util.Math`:
- `Math.max()` and `Math.min()`
<pre><code>import java.util.*;
interface M{
	static void main(String[]x){
		int a = 20, b = 30;
		System.out.println(Math.max(a,b));
		System.out.println(a>b?a:b);
		System.out.println(Math.min(a,b));
		System.out.println(a<b?a:b);
	}
}

# A clever way to replace `Math` functions

You can shorten `if-else` statements through the `a?b:c` syntax, where `a` is the statement of `if`, `b` is the result of `if`, and `c` is the result of `else`.
