I've been trying to make first example program work for about an hour now and I've re-typed it multiple times but it still gives me the same error
ExampleProgram.java:3: error: cannot find symbol
System.out.printIn("Hello World");
And the arrow is pointing at the period (.) after out. Anyone can help me?
