Example 1: string to int java

int result = Integer.parseInt(number);

Example 2: how to convert string to int in java

There are two methods available in java to convert string to integer.
One is
Integer.parseInt() method and another one is
Integer.valueOf() method. Both these methods are static methods
of java.lang.Integer class. Both these methods throw
NumberFormatException if input string is not a valid integer.
