IntelliJ IDEA之常用模板

 1 public class templateTest {
 2     //模板一：psvm
 3     public static void main(String[] args) {

 5         //模板二：sout
 6         System.out.println("Hello!");
 7         //模板二的变形：soutp/soutm/souv/xxx.sout
 8         System.out.println("templateTest.main");
 9         System.out.println("args = " + args);
10         int num1 = 10;
11         System.out.println(num1);

13         //模板三：fori

16             System.out.println(arrays[i]);

34         }
35 
36         //变形：array.fori （正序遍历）
37         for (int i = 0; i < array.size(); i++) {

53         }
54 
55         //变形：inn
56         if (list != null) {
57 
58         }
59 
60         //变形：xxx.nn/xxx.null

70     //模板六：prsf
71     private static final int n= 3;
