Boolean parseBoolean() method in Java with examples

Last Updated : 01 Oct, 2018

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:

JAVA

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:

JAVA

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:

JAVA

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
