Misplaced semicolon in for loop [closed]

by

When you do this: for(i=0;i<n;i++); you are essentially doing this: for(i=0;i<n;i++) {}. This translates to a loop with no body.

This also happens for while loops: while(..);{<Foo>}. The extra ; will make execute only once.

The same goes for if statements. Doing if(a==b);{<Foo>} will still execute <Foo> for the same reason. If a == b, then, the empty statement will be taken into consideration. Afterwards, <Foo> will be executed. This can give the wrong impression that Java will treat a false as a true since if a != b, then, <Foo> would still be executed.
