Java Boolean parseBoolean() Method

The parseBoolean() method of Boolean class returns the string argument as a Boolean. The value is returned true if the argument is equal to the string “true” otherwise, for null or any other string argument, it returns false.

Syntax:

Parameters:

A String parameter s is passed.

Return Value:

The logicalXor() method returns the Boolean represented by the string argument.

It returns true, if the string argument is not null and is equal (ignoring case) to the string “true”.
It returns false for null for any other argument other than true.

Example 1

  public class BooleanParseBooleanExample1 {      public static void main(String[] args) {          String str1 = “false”;          System.out.println(“String value = “+str1);          System.out.println(“String hash code value = “+str1.hashCode());          //it will return String argument as boolean          Boolean b1 = Boolean.parseBoolean(str1);          System.out.println(“Boolean value = “+b1);          System.out.println(“Boolean hash code value = “+b1.hashCode());      }  }  

Test it Now

Output:

String value = false  String hash code value = 97196323  Boolean value = false  Boolean hash code value = 1237

Example 2

  import java.util.Scanner;    public class BooleanParseBooleanExample2 {      public static void main(String[] args) {          Scanner scanner = new Scanner(System.in);          System.out.println(“True/False:”);          System.out.println(“Q. Tal Mahal is located in Delhi.”);          System.out.print(“Ans “); String str1 = scanner.next();              Boolean b1 = Boolean.parseBoolean(str1);              int b2 =b1.hashCode();          System.out.println(b2);              if (b2 ==1237) {                  System.out.println(“Correct answer.nAs Taj Mahal is located in Agra nor in Delhi.”);              } else if(b2 ==1231) {                  System.out.println(“Incorrect. Because Taj Mahal is located in Agra.”);              }          }  }  

Output:

True/False:  Q. Tal Mahal is located in Delhi.  Ans true  1231  Incorrect. Because Taj Mahal is located in Agra.

Example 3

  import java.util.Scanner;    public class BooleanParseBooleanExample3 {      public static void main(String[] args) {          Scanner scanner =  new Scanner(System.in);          System.out.print(“Enter any String value : “);          String str = scanner.next();          Boolean b1 = Boolean.parseBoolean(str);          int val = b1.hashCode();          if(val==1231){              System.out.println(“Boolean value is true”);          }          else if(val == 1237){              System.out.println(“Boolean value is false.”);          }        }  }  

Output:

Enter any String value : reema  Boolean value is false.

For any String other than true, parseBoolean() method will return false.
