Java source code examples

To check a System property has a value true or not we can use the Boolean wrapper class.

public class BooleanWrapper {
	public static void main(String[] args) {
		boolean bool = Boolean.getBoolean("os.name");

		System.out.println(bool);
	}
}

This would return true only if the System property exist and has a value equal to true. All other cases this would return false.
