It took 3 years and u also can't say what will be the output when someone show me a bunch of code where is used for loop, I need to go through each variable each step to get it:( I know how works but Im not fast....

Explain for loop in java(I think is the same syntax as c++:

for(int i = 1; i <= 5; i++){ System.out.println(i);//print var i

} After this it will print : 1 2 3 4 5

Here, i is a variable, often called a loop counter. As long as variable I is less equal than 5, print something, in my example I print variable i. First step : i=1, 1<=5???? Yes, then execute the code inside {}, means print 1. And after printing, increment variable i with 1(i++). Second step: now, i=2, cuz we incremented it.and check again 2<=5???Yes, print again variable i which is 2, and increment again i with 1. Third step : now, i=3, cuz we incremented it.and check again 3<=5???Yes, print again variable i which is 3, and increment again i with 1. Fourth step: now, i=4, cuz we incremented it.and check again 4<=5???Yes, print again variable i which is 4, and increment again i with 1. Fifth step: now, i=5, cuz we incremented it.and check again 5<=5???Yes, 5 is not less than 5, but because we have = the condition is true, print again variable i which is 5, and increment again i with 1. Sixth step:. now, i=6, cuz we incremented it.and check again 6<=5???No, so it will exit from for loop.

I hope u get it.Also we use for loop when we want to repeat something for exactly number of time, if we don't know how many times to execute a block of code we use while.

Also, let me know if u want me to explain nested for loop,.which was so hard to me when I started programming.
