initialization value problem

[ravian]

Hi,

I am confused about the initialization values in Java. I tried the following code and got an error:

Code:

boolean flag;
System.out.println("Printing boolean flag's value: "  + flag);

Exception:

Code:

The local variable flag may not have been initialized

I assumed that flag will have false in it. I tried a boolean array and it had false in all the indexes by default.

Please guide me.

Thanks a lot.

it depends on what you want.. if you want it to be false in the start of your program, initialize it..

boolean flag=false;

This behavior doesnot work with local variables .. If you have code like this then it will be perfectly okay

Code:

public class NativeTypeInitializationDemo {
	public boolean flag;
	
	NativeTypeInitializationDemo(){
		System.out.println("apple" + flag);
	}
	
	public static void main(String[] args){
		new NativeTypeInitializationDemo();
	}
}
