String to Int in Java 20

In Java 20, you can convert a string to an integer using the Integer.parseInt() method. Here's how to do it with some examples:

Example 1:

String myString = "42";
int myInt = Integer.parseInt(myString);
System.out.println(myInt);

Output: 42

Example 2:

String myString = "123";
int myInt = Integer.parseInt(myString) + 7;
System.out.println(myInt);

Output: 130

Example 3:

String myString = "Hello";
int myInt = Integer.parseInt(myString);
System.out.println(myInt);

Output: NumberFormatException, because "Hello" cannot be converted to an integer.
