Convert String to Boolean - A Java Code Example

Do you need help with your Java programming?

Click here for instant help with your Java code.

There's actually two ways to do a string to boolean conversion. Either you can create an instance of the wrapper class Boolean with a string value as argument to the constructor and call the method booleanValue(), or you can do as in the example below:
call the static method parseBoolean() of the wrapper class to convert the string value to a boolean.
Either way, the string value sent in has to be either 'true' or 'TRUE' to result in a boolean with the value of true, but it doesn't have to be 'false' to result in a false boolean value.
It actually makes sense that any other string value than 'true' or 'TRUE' will result in a return value that is set to false.

/**
* Main.java
*
* @author www.javadb.com
*/
public class Main {

    /**
     * String to boolean conversion
     */
    public void convertStringToBoolean() {

        String strBoolean = "true";

        //Do the String to boolean conversion
        boolean theValue = Boolean.parseBoolean(strBoolean);

        System.out.println(theValue);
    }

    /**
     * Starts the program
     *
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().convertStringToBoolean();
    }
}
