String To boolean In Java - parseBoolean()

Chapter: String Handling Last Updated: 13-08-2016 13:29:27 UTC

Program:

            /* ............... START ............... */
                
public class JavaStringToBoolean {
	public static void main(String[] args) {
		// String Objects
		String str = "false";
		// Case does not matter for conversion
		String str2 = "TrUe";

		// String to boolean conversion
		boolean bvar = Boolean.parseBoolean(str);
		boolean bvar2 = Boolean.parseBoolean(str2);

		// Displaying boolean values
		System.out.println("boolean value of String str is: " + bvar);
		System.out.println("boolean value of String str2 is: " + bvar2);
	}
}
                /* ............... END ............... */
        

Output

boolean value of String str is: false
boolean value of String str2 is: true

Notes:

  • The java.lang.Boolean.parseBoolean(String s) parses the string argument as a boolean. The boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".
  • Syntax : public static boolean parseBoolean(String s).
