How do I convert a String to an int in Java?

Explanation

We can convert a String to an int in Java. By using the following statement. And using Integer.parseInt method. 

String string_studyexperts = "1234";


int hoo = Integer.parseInt(string_studyexperts);


And if you know the Java documentation you will notice that the “catch” is that this function can throw a NumberFormatException. Which of course you have to handle:

int hoo;
try {
   hoo = Integer.parseInt(string_studyexperts);
}
catch (NumberFormatException e)
{
   hoo = 0;
}

Also, you can do this with the following:

import com.google.common.primitives.Ints;

int hoo = Optional.ofNullable(string_studyexperts)
 .map(Ints::tryParse)
 .orElse(0)
