The doubt is that in false statement the output is This is executed & in true statement also the output is the same... plz help

Question

public class Myclass {
public static void main(String[] args) {
boolean b;
b = false;
System.out.println("b is " + b);
b = true;
System.out.println("b is " + b);
if (b)
System.out.println("This is executed ");
b = false;
if (b)
System.out.println("This is not executed ");
System.out.println("10 is " + (10 > 9) );
}
}
// it's output should be different why is it same in both cases.

Answer 1

@Lucky, we can do that, but having two if case with different condition would be redundant I guess, I personally would take the if...else way, but since you said you prefer using if case only, well, here you go mate:

public class Myclass {
public static void main(String[] args)
{
boolean b;
b = false;
System.out.println("b is " + b);
b = true;
System.out.println("b is " + b);
if (b)
System.out.println("This is executed when b is true");
b = false;
if (!b) // <- Note the NOT operator (!)
System.out.println("This is executed when b is false ");
}
}

Answer 2

public class Myclass {
public static void main(String[] args) {
boolean b;
b = false;
System.out.println("b is " + b);
b = true;
System.out.println("b is " + b);
if (b)
System.out.println("This is executed ");
// The line following the if(b) will
// only be executed if the b variable
// value is true, since you assigned
// b = false, it is not executed.
b = false;
if (b)
System.out.println("This is not executed ");
System.out.println("10 is " + (10 > 9) );
}
}

You can also use if...else like so,

boolean b = false;
if(b)
System.out.println("It's true!");
else
System.out.println("No! it's false");

Answer 10

Are you talking about System.out.println("b is" + b)
and System.out.println("b is" + b)? they are same but you can declare 2 different bolleans. bollean a = true; bollean b = false; and it will be System.out.println("b is" + a)
System.out.println("b is" + b) that is solution if you are talking about that. :p

Answer 11
