From where did you get this code? The first assignement is unnecessary, because on second line you reassign a new value ( 5 instead 3 ) to 'i'... And the loop defined on second line is a complex declaration loop also unnecessary, because it's equivalent to: 'for (i=5; i!=1; i--)', as testing 'i<i*i' is always true while i is different of one ^^ Anyway, the loop print an undeclared/unassigned variable 'l' five times ( first i==5, second 4... finally 2, stopped when i==1 ).

@Visph it's a Java challenge quizz, hence the unnecessary assignment 😉

@Siddahart Upadhyay answer isn't right, as there is 2 variables in the example, 'i' and 'l', not only one "l" ^^

then the program should show an error due to uninitialized variable I so no output for this question

@Visph the loop stops when i is 1, not 0.

Output for this code will be 5432 because I=5 checks the condition and it's satisfies and print it and the process continues till 1 and stop because it happen like this 5<25 True 4<16 true 3<9 true 2<4true 1<1 false
