https://code.sololearn.com/cDeE2563TWhb/#java i searched for good answer but can't find any.

boolean b = false; if (b =! b) → 0,2,4,6,8 boolean b = true; if ( b=! b) → 1,3,5,7,9 boolean b = true; if ( b = b ) → 0,1,2,3,4,5,6,7,8,9

@Frederick when b = !b it puts the value which is not b every time the loop runs. And that's !b. I wasn't trying !=.

@Patrik I know some of it but still wanna get the idea. I don't have lot of time to study about these topics and would search on google but thought why not just ask here. Thanks @noob, jasmin, Sakib.

You ask why but you know the answer ;-)

well, the first thing is that =! should be written !=. the next thing is the use of the = which usually means is assigned, except in visual basic and use of the == which usually means equals, except in visual basic therefore, the lines that look like boolean =! boolean evaluate to true while the line that looks like boolean = boolean means boolean is assigned to boolean which is false by definition, so the last line that evaluates to true prints the line of odd integers. I am trying to figure out how you got this code to compile at all

Try to add a newline in print(), that will help ;-)

initially...b has value 1... in 1st iteration, if condition changes d value to 0 ... condition becomes false and the argument is skipped and 0 is not printed... in next iteration reverse scenario occurs and condition becomes true and 1 is printed... this is repeated through the loop... hope dis answers the question
