IntegerparseInt

Integer.parseInt() is a method in Java that is used to convert a string representation of a number into an integer. It takes a string as input and returns an integer value. If the string is not a valid integer, then a NumberFormatException is thrown.

Syntax:

int num = Integer.parseInt(str);

where num is the integer value and str is the string to be converted.

Example:

String str = "123"; int num = Integer.parseInt(str);

In this example, the string "123" is converted to an integer value of 123 using the parseInt() method.
