Initial value of boolean

• If we're talking about a member variable then the value will be false.
• If we're talking about a local variable then the value needs to be explicitly initialized before being used.

The same holds for all other primitive & any reference data types. Reference data types will be initialized to null.

Do note that any final member variables will need to be initialized at the time of creation or in the constructor.

Try the following code sample

public class Test
{
	static boolean b1;//try final here
	static Object o1;//try final here

	public static void main(String args[])
	{
		boolean b2;
		Object o2;

		System.out.println(b1);
		System.out.println(o1);
		//System.out.println(b2);//uncomment this line
		//System.out.println(o2);//uncomment this line
	}
}
