convert variable from string to int in java

  int num = Integer.parseInt(stringVar);

This code is written in Java, and it is used to convert a variable from string to int. The code is creating a new int variable called “num” and assigning it the value of the “stringVar” variable after it has been converted from a string to an integer. The code uses the built-in Java function of Integer.parseInt to convert “stringVar” to an int. This is an efficient way to convert a string to int without having to manually input each specific character.
