How do I convert a string into an integer?

I have a textbox I have the user enter a number into:

```
EditText et = (EditText) findViewById(R.id.entry1);
String hello = et.getText().toString();

```

And the value is assigned to the string `hello`.

I want to convert it to a integer so I can get the number they typed; it will be used later on in code.

Is there a way to get the `EditText` to a integer? That would skip the middle man. If not, string to integer will be just fine.
