Java Integer.parseInt() is a static method in the Java Integer class that converts a string representation of a number into its Java int equivalent. It throws a Java NumberFormatException if the string is not a valid number. Introduced in Java 1995 with Java 1.0, parseInt() is used extensively for parsing user input, configuration files, and data streams where numbers are stored as strings and need to be converted to integer values.
