2.for cycle

   when we need a fori loop, we can enter the number of times we want to loop, for example, 100, and then hit .fori. You can get:

For (int I = 0; I < 100; iTunes +) {} 3.try-catch statement

   if we call try-catch on a function, we can finish writing that when the function call is not marked with a semicolon, hit .try. You can get:

Try {foo ();} catch (Exception e) {e.printStackTrace ();} 4. Non-empty judgment

   when we need to judge that a variable is not empty, we just type in the variable, and then type .nn, and we get the if statement of! = null.
