Are any difference between write java programs with different application?

Question

I mean, I practice with NetBeans 8.2 and when I tried to execute the line System.out.printIn("Hi"); , the program indicated that was wrong, then when I look for suggestions I found the next code System.out.print("Hi"); and it works fine.

I've not noticed any differences in the 4 I've used. It is possible you had the wrong one of these: printIn or println. One has a captial i instead of the correct lowercase L. One of the beginner's codes I fixed did this and it took a while to figure out.
