Convert this tiny php class to adequate java one.

Start file

<?php
class Foo
{
	private $var1;
	private $var2;

	public function Foo($val)
	{
		$this->init($val);
		$this->doSomething();
	}

	private function init($val)
	{
		$this->var1 = $val;
	}
	
	private function doSomething()
	{
		$this->var2 = sqrt($this->var1);
	}

	public function getResult()
	{
		return $this->var2;
	}
}
?>

End file

public class Foo
{
	private double var1;
	private double var2;

	public Foo(double val)
