The parseBoolean() method of Boolean Class is a built in static method of the class java.lang.Boolean which is used to convert a given string to its boolean value.

Syntax:

Boolean.parseBoolean(String value)

Parameters: It takes one parameter value of type string which contains the value which is to be converted to boolean.

Return Value: It returns a primitive boolean value. It returns the true if the given value is equals “true” ignoring cases. Else it returns false.

Below are java code to illustrate parseBoolean() method:



Example 1:




class GeeksforGeeks {
  
    // Driver method
    public static void main(String[] args)
    {
  
        // string value
        String value = "TrUe";
  
        // parseBoolean using parse Boolean() method
        boolean result = Boolean.parseBoolean(value);
  
        // printing the result
        System.out.println(result);
    }
}
Output:
true

Example 2:




class GeeksforGeeks {
  
    // Driver method
    public static void main(String[] args)
    {
  
        // string value
        String value = "true";
  
        // parseBoolean using parse Boolean() method
        boolean result = Boolean.parseBoolean(value);
  
        // printing the result
        System.out.println(result);
    }
}
Output:
true

Example 3:




class GeeksforGeeks {
  
    // Driver method
    public static void main(String[] args)
    {
  
        // string value
        String value = "gfg";
  
        // parseBoolean using parse Boolean() method
        boolean result = Boolean.parseBoolean(value);
  
        // printing the result
        System.out.println(result);
    }
}
Output:
false
