Kotlin Standard Library Cookbook

Getting ready

Let's consider the following Java code:

int value;try {    result = parseInt(input);} catch (NumberFormatException e) {} finally {    result = 0;}

It declares an int result variable. Next, it tries to parse the string value to the integer with the Integer.parseInt() function, and if it succeeds, it assigns the result to the value variable. If the parseInt() fails to parse the string, a default value of 0 is assigned to the value variable.
