parseBoolean()方法在Java中的重要性是什么？

public static boolean parseBoolean(String s)

import java.util.Scanner;
public class ParseBooleanMethodTest {
   public static void main(String[] args) {
      System.out.print("Are you ready to play cricket(true/false)?");
      Scanner scanner = new Scanner(System.in);
      String str = scanner.nextLine();
      scanner.close();
<strong>      //</strong> Convert the user input into boolean<strong>
</strong>      boolean answer = Boolean.parseBoolean(str);
      if(answer) {
         System.out.println("Yes, I am ready to play cricket");
      } else {
         System.out.println("No, I am not yet ready");
      }
   }
}

Are you ready to play cricket(true/false)? true
Yes, I am ready to play cricket
